How to choose the color of the laser pointer
If you are not familiar with the technology or the way they are used for a particular application, knowing which laser to buy can be tricky, which may seem a little daunting. Here, we will learn about different types of green laser pointer, different beam colors and different output powers; so you can better understand which laser is suitable for your specific needs. Laser pointer is a general term, which can be divided into green, red, blue, blue-violet, and yellow according to color. Red and green are the most common. Yellow laser pointers are unstable and efficient due to the complicated manufacturing process. Low, extremely rare in the market.

The laser pointers currently on the market are generally composed of two parts: a laser pointer and a signal receiver, and are powered by a dry battery. There are few rechargeable laser pointers. In daily applications, people often need to enter the required files into the USB flash drive, and then transfer the things in the USB flash drive to the computer during use, and then use the high power laser pointer to explain. In this way, people must bring a bunch of things such as USB flash drives, batteries, laser pointers, etc. at the same time when they travel. Therefore, people very much hope that there will be a laser pointer that integrates all these functions. Lidar is a radar system that emits laser beams to detect the position and speed of the target and other characteristic quantities. Its working principle is to transmit a detection signal (laser beam) to the target, and then compare the received signal (target echo) from the target with the transmitted signal. After proper processing, relevant information about the target can be obtained, such as Target distance, azimuth, altitude, speed, attitude, even shape and other parameters, so as to detect, track and identify aircraft, missiles and other targets. It consists of a laser transmitter, an optical receiver, a turntable, and an information processing system. The laser converts electrical pulses into light pulses and emits them. The optical receiver then restores the light pulses reflected from the target to electrical pulses and sends them to the display.
