How to tell the difference between a photoelectric mouse and a laser mouse?

This question puzzled a lot of people, Shenzhen Rui Ding reminds everybody, want to know the difference between them, we must first know that the photoelectric mouse and the laser mouse's distinguishing standard is according to the mouse engine's difference.

1, the optical mouse working principle is to detect the displacement of the mouse through infrared, and then the displacement signal to the electrical pulse signal, and then through the program processing and conversion to control the screen cursor arrow movement.

2, most of the optical mouse are red LED light as a light source, because in the visible spectrum, the wavelength of the red light is the longest, its penetration is also the strongest (that is, we often say that anti-jamming). There is still a Blu-ray led on the market, in fact, there is no gap between the two, unless there is progress in technology, the only difference between the two is the color difference.

3, the current market on the market there are infrared light source (that is, not visible light), is misunderstood by many people as a laser mouse, but he is also a common optical mouse, only the use of the invisible light source, the overall power consumption and the effect and the normal red mouse is the same.

4, the laser mouse working principle and the optical mouse is the same, but the working mode is different, the laser mouse working mode is through the laser irradiation on the surface of the object produced by the interference fringes formed by the light spots reflected on the sensor, and the traditional optical mouse is irradiated by the rough surface of the shadow generated by the results.

5, so the general laser mouse because the laser can produce a greater contrast to the surface of the image, so that the image of the sensor to be more easily identified, so that the mouse positioning accuracy is stronger.
