What is a laser mouse?

What is a laser mouse? The laser mouse is actually an optical mouse, but it uses laser instead of ordinary LED light. The advantage is that more surfaces can be used because the laser is Coherent Light, a single wavelength that maintains its intensity and waveform even after long-distance propagation, while the LED light is Incoherent Light (incoherent light) .

The process of the laser mouse sensor obtaining images is based on the fact that the light spots formed by the laser irradiation interference fringes generated on the surface of the object are reflected on the sensor, whereas the conventional optical mouse is obtained by irradiating shadows generated on the rough surface. Therefore, the laser energy produces a greater contrast to the surface image, thereby making the image obtained by the “CMOS imaging sensor” easier to recognize and improving the positioning accuracy of the mouse.

Advantages compared to ordinary optical mouse 1. The interface that the mouse passes is generally known as the mouse that can be used and used comfortably in those interfaces. The desktop is still a very uniform interface, but rough interfaces such as clothes and optical mice do not move, because the rough interface reflects little light and the mouse sensor receives no signal. However, the laser is not the same, because it is a beam of light, as long as there is a reflection point, it can be completely unimpeded, tiles, clothes, palms are all of these words, if your desk has a layer of 5--8 mm glass, the laser One mouse is OK on the glass, because the laser light can pass through the glass and reflect back through the desktop, allowing the mouse sensor to receive the light signal. Of course, a completely transparent glass that floats is not enough because it is equivalent to having no reflective interface, but you can use a rag to brush across completely transparent glass. Even a little stain can be seen on a laser mouse.

2. The resolution of the mouse is also the sensitivity of the mouse. Units are represented by DPI. At present, most of the ordinary optical mouse's DPI is 800, with a better sensor can support up to 1000 or so, our current market is more Sony and IBM pirated mouse is basically 400DPI. The laser mouse can support up to 5700 DPI, and the lowest grade laser mouse can support up to 1600.

3. The accuracy of the mouse is the positioning of the mouse, which is the position of the cursor when you press the mouse button. This can be best demonstrated when playing the game, especially if you need a highly-positioned shooting game. If you aim at the enemy to fire, if the accuracy is not good, the cursor will run away, aiming and hitting the enemy. The current high-end professional gaming mouse is mostly a laser mouse, most notably Logitech and Microsoft. As for the difference between the accuracy of a laser mouse and an optical mouse, you should try it on your own computer or test it with professional test software.

Coaxial Cable is a type of cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Many coaxial cables also have an insulating outer sheath or jacket. The termcoaxial comes from the inner conductor and the outer shield sharing a geometric axis. Coaxial cable was invented by English engineer and mathematician Oliver Heaviside, who patented the design in 1880. Coaxial cable differs from other shielded cable used for carrying lower-frequency signals, such as audio signals, in that the dimensions of the cable are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a radio frequency transmission line.
