USB Optical Mouse Works

Optical mouse with mechanical mouse, the biggest difference is that its location in different ways.

Optical mouse works: inside the optical mouse has a light emitting diode by the light emitting diodes light, bottom surface illuminated optical mouse (this is the reason why the mouse bottom will shine). Optical mice are then reflected back to the surface at the bottom part of the rays, after a group of optical lenses, transferred to a light-sensitive devices (micro-imaging device) imaging. In this way, as the optical mouse moves, its movement would be recorded as a set of coherent images taken at high speed. Using a dedicated image analysis chip inside the optical mouse (DSP, digital microprocessor) uptake on the trajectory of a series of image analysis and processing, through an analysis of the change of image feature point location on to determine the direction of movement of the mouse and move distance, thus completing the positioning of the cursor.
