 Imagine a world where the physical and digital realities are merged, can coexist, and you can move seamlessly between these worlds. This is the promise and potential of augmented reality. Hello, my name is Parath Rajagopalan and I am the Director of Strategic Marketing at ST Microelectronics. Thank you for viewing the laser beam scanning for augmented reality smart glasses technology demonstration. It's a pleasure to share with you today a brief presentation and demonstration of a very exciting technology which we presented at the CES 2021 virtual event in the ST virtual booth. Before jumping into the technology demonstrator, let me first share with you a quick background or refresher on laser beam scanning technology. This is quite a busy slide and I'll walk through this slowly. So starting at the top left, you'll see an illustration of the operating principles of LBS or laser beam scanning. Quite simply, it combines the pre-modulated light from the three lasers which go through collimating and beam combining lenses onto a MEMS mirror scanner which then performs a rock to scan and the full image is delivered to the eye or any other surface. In the block diagrams below, we show two key aspects of the solution. One is the electronic subsystem and the other is the optical light engine. Now the electronic subsystem includes three key devices from ST which are the MEMS mirror driver, the laser diode driver and a digital controller which provides a closed loop control of the imaging system. This electronic subsystem then connects to the optical light engine in which the key elements or the laser diodes which is developed by our partner and along with ST, laser alliance funding member OSRAM, also included are beam combining optics, some of which is noted above in the illustration of LBS and of course the MEMS micro mirrors provided by ST. Now these are then integrated into a compact PCB shown below which is then coupled into a waveguide and this waveguide is been developed by a partner and also a laser alliance funding member Displex. This PCB is embedded in the temple of the glasses. Now on the right hand side are some of the key characteristics of the laser beams can solutions from ST. Now in addition to multiple technology platforms for the MEMS mirrors including electrostatic, electromagnetic, thin film piezo and including as well high performance laser diode driver as well as a controlled ASICS ST has also developed really optics which optimizes the beam profile onto the coupler of the waveguide. Now in this slide we illustrate over here and you can see the actual glasses that embodies the key technology elements just discussed. The light engine is embedded in the right temple of the glasses. Some people call the temple arm. Now hopefully you can see from this 360 image how laser beams can solutions can lend itself to the creation of stylistic and a very good form factor AR smart glasses. These look nearly like any of the glasses that you can buy in the market. This slide shows several additional images of the technology demonstrator as well as what it looks like when worn. Again you can see the glasses are quite stylish and can be worn anywhere and quite frankly people won't be able to readily distinguish these as AR glasses from regular eyeglasses. Of course this is just a technology demonstrator and I'm sure many of you out there can use LBS technology to create even smaller form factor AR smart glasses. These photos capture the image as seen through the glasses although as many of you know it is difficult to capture images using a CMOS image sensor based camera and then re-display these or map these onto the color palette of models or displays. These images still do show however very good image quality as seen through the glasses. The field of view is more than adequate, the brightness is excellent, the text quality is quite good. Regrettably we're not able to have physical demos this year but I can tell you the images are much better when actually viewed with the eye. Hopefully as noted in the break news we'll be able to meet again in person soon and you can try out these glasses for yourselves. This image shows an example use cases for these glasses as worn and in a live environment. Once again you'll see a rather pleasing form factor and as I mentioned earlier the volume of the size of these can be further reduced. And finally here are some of the key specifications of the demonstrator. Some of the key ones include good, actually that would say more than adequate, field of view of 30-degree diagonal which is more than sufficient for applications that requires to display information and content such as graphics, text overlay, symbols and other informatics. And as I mentioned earlier the brightness is excellent at 1300 nits or candles per square meter which is quite significant as it lends the part to be designed with highly transparent lenses rather than heavy tint in order to achieve high ambient contrast ratio. And the demo clocks in in just under 58 grams of weight which is very important to ensure all the wearability and user comfort. So let me thank you all for your attention. I hope you found this presentation on laser beam scanning for AR smart glasses of interest. And if you have any questions or would like more information please feel free to talk to me, my colleague or our partners at the contact information below. Thank you.
