 Hello, I'm Sylvie Rigaret. I'm working in ST, an imaging division where I am in charge of the marketing and technical support team in EMEA. Today, I will present you our ST Time of Flight Ranging Sensor, also called FlightSense. Here is the agenda. After a short introduction, I will briefly explain the use cases and applications. Then, we will go through the Time of Flight mass market roadmap and complete this presentation with some highlights on the new products features. ST is a pioneer and a worldwide leader in time of flight solutions. We have already developed our fourth generation of all-in-one top solutions and we deployed them since five years. Our products are already invaded on more than 170 phones with more than 15 smartphone OEMs. But we have also in parallel hundreds of non-wireless end products on which our flightSense solutions are used. We have already deployed more than 42,000 evaluation kits and sold more than 1 billion of units. We are mastering the complete hand-to-hand supply chain from the Time of Flight Pixel expertise up to the advanced packaging, know-how and manufacturing. Let me explain you the Time of Flight principle. This is a method for measuring the distance between the sensor and an object that is based on the time difference between the emission of a vexel light signal and its return to the sensor after being reflected by the object. The photons emitted by the laser are reflected on the target and trigger an avalanche when they are coming back to the SPAD array, SPAD standing for single photon avalanche diode. This means that the time between the emission of the photons and the avalanche is measured and translated into a target distance. This technology is a proprietary technology and is independent of the target size, color and reflectance. It's very fast as the distance can be computed in a few milliseconds and low power, meaning that this principle is fully adapted to battery operated systems. The illumination is based on a truly invisible 940 nanometer, meaning that the user will not be distracted by such illumination. ST Time of Flight sensors are all-in-one solutions, means that we embed on the same module the illumination and the sensor. So there is no need for external components and thanks to this optimization, we can propose a perfect mix of size, performance and cost. So the top sensor embeds the emitter, which is a vexel, vertical cavity surface emitting laser. It's a high-power vexel following the full class 1 safety. We can integrate some advanced optics with some integrated infrared filter depending on the product reference. And on the receiver part, we have the SPAD array, single photon avalanche diodes. We have also the vexel driver and all the RAM and ROM necessary to run the algorithms. The complete module is developed for the front-end part in France and all the final test and module assembly is done in ST line bait in Chenzen. Our FlightSense products benefits from the ST longevity program. It means that we commit a minimum of 7 years mass production from the product introduction date. As you can see, most of our products are part of this program since January 2019. Further information on this 7 years longevity program can be found on ST.com. FlightSense use cases and applications. Here are some examples of typical applications in which ST FlightSense products can be used. On the left, the camera assistance with laser autofocus and touch-to-focus use case. Our products can be used also for ranging and proximity by computing a very accurate distance up to 4 meters. It can be used also for multi-spectral and light flicker measurement and correction. For face identification, our products can propose the perfect and optimized mix between cost, power and size. For instance, face anti-spoofing use case. Our products are used also for presence and user detection in front of tablets, laptops. This is important for security and comfort but also for power saving and eye protection. And last one is the depth map and augmented reality and virtual reality thanks to some advanced gesture recognition. The FlightSense sensors allow different main functions. They can be used for ranging measurement, for proximity sensing, for multi-zone distance measurement, for multi-target distance measurement, for presence detection and free distancing. They can enable multiple use cases, very large ones like sailing and cliff detection, but also content analysis and load management. They can be used also for any kind of control like gesture control or volume control, but also occupancy detection, parking occupancy, people counting and SLAM. Of course, they can be used to develop unlimited markets. There is an unlimited number of markets and applications for which our FlightSense products can be used. Here is just an example of them with laptops and tablets for presence detection, but also smart home for sets, dispensers, white goods with proximity detection. Our products can be used also for stock management, for logistics, warehouse, tanks, vending machines also. We have also a huge number of use cases on robots with service robots and cleaning robots. Again, this is just an example and we count on our customers to enable a lot of new use cases. Let's focus now on the FlightSense mass market roadmap. This FlightSense roadmap highlights the five FlightSense sensors that are today in mass production and also the next generation that will be promoted early next year. All these products are represented with a series of pictograms that correspond to the main function. These products are also represented depending on the maximum distance measurement in centimetre on the X-axis. Let's start on the left side of the roadmap with the VL618V1. This proximity sensor is capable to measure distances up to 50 centimetres and is offering a very good linearity at close distances. The next one is the VL53L06. This ranging sensor can be used to measure distances up to two metres and is also offering very good performance under ambient light environment. The VL53L36 is a new proximity and multi-target sensor that is introduced on the market this year. This sensor indeed, thanks to the histogram function, is capable to measure the distance of several objects and for each object it returns the exact distance with the sensor. This FlightSense sensor has also a smudge correction capability and very good performance under ambient light environment. If you need to measure longer distances, you can use the VL53L1CB. This one is also a new FlightSense sensor that we have introduced on the market this year. This long distance and multi-target sensor can measure distances up to 3.2 metres. You have on this sensor the possibility to program the field of view with a maximum field of view at 27 degrees. This sensor has also a multi-zone sensor with a sequential 2x2 zones allowing on each zone to detect several objects and to return the exact distance with these objects per zone. This sensor has also the smudge correction and very good performance under ambient light conditions. If you need to further increase the maximum distance measurement up to 4 metres, then you can use the VL53L1X that is a long distance sensor. This sensor has also the capability to have a programmable field of view and has also very good performance under ambient light conditions. All these products are today in mass production and you have a 6th product that is mentioned in this roadmap that is the VL53L5CX. This multi-zone sensor will be promoted on the market early next year and thanks to its 64 zones you have the capability to use this sensor for mini depth map application allowing maximum distance measurements up to 4 metres. This table gives further information on each flight sense product like the field of view, the power consumption, the size of the drivers and the size of the module. As you can see the VL6180V1 has a very low power consumption at 1.7 mA and has a very good, extremely good linearity at close distance from 2.5 cm. The L0CX and L3CX have exactly the same size of the modules and are pin-to-pin compatible. The L3CX has in addition a complete immunity against crosstalk above 80 cm and below 80 cm we have an automatic smudge compensation. The L1CX and L1CB have also exactly the same size of the module and are pin-to-pin compliant. You can configure the field of view. This is configurable by software. You have an optic lens on the receiver part for each of these two references and you have also total immunity against crosstalk above 80 cm for the L1CB and a smudge compensation below 80 cm. Highlights on the new product features. The VL53L1CX and VL53L1CB have the capability to program the field of view. It means that you can select a reduced number of spots for the region of interest sensing area to limit the viewing angle of the sensor device. This means that you will have to set a region of interest meaning positioning the reduced sensing area at a selected place on the spatter ray to detect and measure the distance of any objects in this specific ROI field of view. As you can see, the setup of the ROI zone is fully configurable in software. The minimum size is 4x4 spads corresponding to a diagonal field of view of 15° up to 16x16 spads meaning the total array corresponding to a maximum diagonal field of view of 27°. You have a specific ROI application note associated to the VL51L1CX available on ST.com. The VL53L3CX and VL53L1CB have the histogram function. It means that they can perform multi-object detection and output the ranging distance for each detected object. Thanks to the technology, the direct time of flight principle, you can measure multiple objects within the sensing area. If you compare to indirect time of flight solutions, these cannot output multiple beams and extract the distance with a correct resolution. So this is a key advantage of the direct time of flight sensors. This function of multi-object detection can be useful if you need for instance to remove the background or to allow a first object detection. Let's go deeper on the histogram architecture of the VL53L3CX and VL53L1CB flight sensors. The histogram is based on 24 beams. A beam is represented as a time window that corresponds to the amount of photons back on the sensor during a certain period of time. In order for an object to be detected, it has to cover roughly three beams, meaning that this is equivalent to roughly 80 cm. That's why we say that the typical depth separation between two objects has to be at least 80 cm to detect two different objects. On the left side of the histogram, we have represented the crosstalk and smudge that corresponds to a certain amount of noise. We use this information to set the threshold, that is the minimum signal for valid target detection. That's why we can say that the histogram allows cover glass crosstalk immunity beyond 80 cm and dynamic smudge compensation. Let's focus now on the crosstalk immunity principle. In the case a cover glass is used, a crosstalk calibration has to be performed to allow a very accurate distance measurement. We distinguish two use cases. Beyond 80 cm, there will be zero impact of the crosstalk from the cover glass on the target. So we have a complete immunity to crosstalk. Below 80 cm, we will have to perform a crosstalk calibration in order to compute the crosstalk level and remove this noise level to the raw range data in order to get a crosstalk-free range information. The VL53L36 and VL53L1CB have dynamic fingerprint smudge compensation function. This is important to consider. In the case you have smudge or dust or fingerprint on the cover glass, that will generate some noise, so some crosstalk. Again, depending on the distance that you need to measure, beyond 80 cm, the smudge will have no impact on the distance measurement thanks to the histogram function. But below 80 cm, you will have to perform a dynamic calibration, meaning to consider the crosstalk increase due to the smudge to calculate this new crosstalk calibration data for smudge compensation and then to remove it from the raw data. For each of our FlightSense products, we have developed a complete ecosystem and several tools in order to allow the customers to evaluate the performance of our solutions. For instance, we propose some expansion boards that we called XNucleo for each of our FlightSense products and those boards are fully compliant to the STM32 Open Development Environment. These boards can be ordered as a standalone board or as a package with the STM32 Nucleo. You can order also standalone breakout boards. These expansion boards can accept breakout boards through connectors or flying wires, but you can also separate these breakout boards in order to use only the mini PCB that is easier to integrate into a customer device. We also propose some examples of cover glasses that you can use for testing and after that for mass production. And we also propose in our tools three different spacers in order to create various hair gaps. All these systems can be ordered and we have a complete, let's say, software tool that is also available for each of our FlightSense products. Last but not least, I encourage you to regularly visit our ST website www.st.com, online marketing, in order to get access to numerous online support tools and also to a set of use cases, webinars and videos. You will find some video examples like calibration free, dirty environment cover glass solutions based on the VL53 L1X, but also some gated started videos with, for instance, the L1X sensor and some videos demonstrating some use cases like people counting using a single ST Time of Flight sensor, the L06 and also a video highlighting smart shelves use case with programmable region of interest on the VL53 L1X. We have also put on ST YouTube channel several videos like the mini LiDAR that is based on 9 VL53 L1X and also a reflector meter example based on the VL53 L06. This is the end of the presentation.
