General Description
The IC is based on an optical bridge technology which provides a non-mechanical detection of movements.
The system detects the optical reflections of an object in front of the sensor by using a function principle called HALIOS® (High Ambient Light Independent Optical System) which is very effective in the suppression of ambient light and also has self calibration capability to eliminate disturbances caused by housing reflections and scratches.
