STMICROELECTRONICS is providing micro-mirrors and control devices for Intel’s Perceptual Computing initiatives.

ST is supplying ASIC control devices, as a well as a tiny MEMS mirror that can move thousands of times per second to scan an infrared light beam, painting an invisible grid on objects in front of it. The light which is reflected back from the object can then be captured and analysed for 3D imaging and gesture applications.

According to ST, the use of MEMS technology creates small and robust systems that have high performance and low energy characteristics ideally suited for a wide variety of consumer applications. This will be critical to creating new and more natural interactions between people and technology, which is one of the aims of Perceptual Computing.

MEMS meld mechanical and electrical principles in tiny machines that can sense motion, the environment or actuate and move liquids. In this case, the mirror is actuated using electro-static principles.

The micro-mirror packs exceptional electro-static actuation, extremely low power consumption, and hardware safety mechanisms that provide protection from hacking and malfunctions, onto the silicon.
