And, with the falling price of the optical mouse, instead of a mechanical mouse and become the market mainstream trend has been unstoppable. Today, the author to the founder of optical mouse machine equipped with a brand as an example, leading everyone to see the scenery inside the optical mouse. The working principle of optical mouse optical mouse mechanical mouse and the biggest difference is the different ways of positioning. The working principle is: in the optical mouse optical mouse has an internal light emitting diode, emitted by the light emitting diode light, illuminating optical mouse bottom surface (which is why the bottom of the mouse will shine and then cause) optical mouse reflected back to the bottom surface of a part of the light,. After a group of optical lens, the transmission to a light sensing device (micro imager) in imaging. So, when the mouse moves, the moving track will be recorded as a set of high-speed shooting coherent image. Finally, using a dedicated image optical mouse internal analysis chip (DSP, digital microprocessor) to a series of image trajectories on the uptake of analysis, through the analysis of the changes of these image feature points, to judge the moving direction and moving distance of the mouse cursor, thus comple
