The answer to this is Optical mouse. 

The reason the answer is optical mouse is because the 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. 

Hope this helped :)
have a great day
