 My name is Guy Amour and I'm a system engineer working at ST Microelectronics Microactuators Division. Today I will present you a short demonstration of ST MEMS murals for later applications. A 3 millimeter diameter reflective area, gold coated, with a resonance frequency of 2.1 kHz. Here you can see the system setup on an optical bench. The system comprised of three main building blocks. One, the optical engine containing the MEMS mirror and a laser block housing a visible collimated red laser for demonstration purpose. Two, the core electronic circuit with ST chipsets for driving, sensing and generating synchronization signal and small STM to run the control loops. An extension debug card is present only for debugging purpose. Three, an external circuit that receives the synchronization signals and modulates the laser according to the mirror position. This board basically emulates a laser application circuit. We have started the system with the MEMS mirror scanning at a full opening angle of 60 degrees field of view and we have activated the laser in a continuous wave mode. For this demonstration purpose we are using a low power visible laser. In a real application we will use a high power infrared laser. Next we will show you how we can control the opening angle changing the field of view. Field of view reduction can be useful to scan an hour scene within the region of interest. To reduce the opening angle we are using a GUI tool that comes along with the evaluation key. The tool allows you to monitor and configure few parameters including the opening angle. Now we will show you how the system can generate pulses of light at specific angles by modulating the laser at configured mirror positions based on synchronization signal generated by ST chipset. We can change the number of pulses within the mirror swing cycle as you can see in the projected image. This concludes our demonstration for today. Thank you for your interest in ST microelectronics MEMS for laser applications.
