What Does Optical Mouse Mean?
Optical mouse is a computer pointing device that uses a light-emitting diode (LED), optoelectronic sensor and digital signal processor (DSP) to detect changes in reflected light from image to image. An optical mouse uses special-purpose image processing chips, as the mouse takes over 1,000 images/ps below the surface level to detect movement through reflected light changes. This allows usable movement data to be generated by the DSP and sensor.
Techopedia Explains Optical Mouse
Because an optical mouse does not have moving parts, it does not need to be cleaned - eliminating mechanical failure. An optical mouse is optimally used on surfaces that reflect but scatter light. Unfrosted glass is a poor surface option because small image irregularity detection is nearly impossible.
