Answer:
An optical mouse is an advanced computer pointing device that uses a light-emitting diode ( LED ), an optical sensor, and digital signal processing ( DSP ) in place of the traditional mouse ball and electromechanical transducer. Movement is detected by sensing changes in reflected light, rather than by interpreting the motion of a rolling sphere.

- An optical mouse is a computer mouse which uses a light source, typically a light-emitting diode, and a light detector, such as an array of photodiodes, to detect movement relative to a surface.
