Description

Using Laser SensorsLaser sensor is an upgraded version of the optical sensor, the wavelength of the laser used in the mouse is 850nm, in the infrared region, we can not see with the naked eye.Laser mouse sensor to obtain the image process is based on the laser irradiation on the surface of the object generated by interference stripes and the formation of light spots reflected back to the sensor to obtain, while the traditional optical mouse is through the irradiation of rough surfaces generated by the shadow to obtain. Therefore, the laser can produce a greater contrast to the image of the surface, thus making the image obtained by the "CMOS imaging sensor" easier to distinguish and improve the positioning accuracy of the mouse.
