SENSOR CHIP FOR LASER OPTICAL MOUSE AND RELATED LASER OPTICAL MOUSE

摘要

A sensor chip for a laser optical module has a plurality of sensor units and a processor. The sensor units sense speckles formed on a working plane and generate image data. A distance between each of the sensors and a closest sensor is not larger than 30 micrometers. The processor processes the image data and generates a display signal, which corresponds to the movement of the laser optical mouse.
