What is a laser mouse

Laser mouse is actually a photoelectric mouse, but is a laser instead of the ordinary led light. The advantage is that the laser is coherent Light (coherent light), almost a single wavelength, even though it is still able to maintain its strength and waveform through long-distance propagation; The light is incoherent Light (incoherent light).

The process by which the laser mouse sensor obtains the image is based on a light spot reflected by the interference fringes of the laser irradiation on the surface of the object, and the traditional optical mouse is obtained by illuminating the shadow generated by the rough surface. Therefore, the laser can make the image of the surface more contrast, so that the "CMOS imaging sensor" image easier to identify, improve the accuracy of the positioning of the mouse.

Advantages compared to common optical mouse

1. Mouse over the interface

The popular point is that the mouse in those interfaces can be used and comfortable to use. The desktop is also a very uniform interface, but rough interface such as clothing, optical mouse basic can not move, because the rough interface reflects very little light, the mouse sensor does not receive the signal. But the laser is not the same, because it is a beam of light, as long as there is a reflection point, it is completely unimpeded, tile, clothing, palms These are just a trifle, if your desk has a layer of 5--8 millimeter glass, put the laser mouse on the glass one is OK, because the laser can pass through the glass through the desktop and reflect back, Let the mouse sensor receive the signal of the light. Of course, the completely transparent glass is not good, because he is equivalent to no reflective interface, but you use a cloth in the completely transparent glass across, even if a little stain, the laser mouse can work on it.

2. The resolution of the mouse

That is, the sensitivity of the mouse, using the DPI to represent units. At present, the majority of ordinary optical mouse dpi is 800, with a better sensor can support up to 1000, we currently market more Sony and IBM pirated mouse is basically 400DPI. And the laser mouse can support up to 5700DPI, the lowest grade of Laser mouse can also support to 1600.

3. The accuracy of the mouse

The

is the positioning of the mouse, which is when you press the mouse button, the cursor positioning. This game can be the best time to reflect, especially the need for high positioning of the shooting game, in the target of the enemy fire if the accuracy is not good, the cursor will run away, aimed at also hit the enemy. The current high-end professional game mouse is mostly laser mouse, the most famous of course is Logitech and Microsoft. As for the laser mouse and the accuracy of the optical mouse is much more than you can take on the computer experience or with professional testing software testing.
