Detailed explanation-1: -An optical mouse is a computer mouse which uses a light source, typically a light-emitting diode (LED), and a light detector, such as an array of photodiodes, to detect movement relative to a surface.
Detailed explanation-2: -What surfaces do laser and optical mice work on? In order to track movement, optical and laser mice shine a light, the CMOS sensor records the pattern, and the process is repeated while comparing the pattern to the previous image. This can happen thousands of times per second.
Detailed explanation-3: -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.
Detailed explanation-4: -The Optical mouse (C) is the mouse that uses laser technology to detect the motion of the ball. Explanation: An optical mouse is the mouse that finds the motion of the ball, accurately, with the help of its laser mechanism.
