Plagiarism of Lidar
A laser is a device that emits a coherent beam through an optical amplification process. There are many types of lasers, including gas lasers, fiber lasers, solid-state high power laser pointer, dye lasers, diode lasers and excimer lasers. Each of these lasers share a set of basic components. Lidar emits a red laser pointer and receives objects that reflect the laser, creating a 3D map of the car's surroundings. Uber said that its lidar is equipped with four lenses-two for laser lasers and two for receiving lasers. Waym lidar is only equipped with a lens that can emit or receive laser light. Waymo said that when Otto told the Nevada State Vehicle Administration in September that its self-driving truck relied on a customized lidar system, its suspicions were confirmed.

Currently only Quanergy is engaged in phased array technology. It integrates n×m micropower lasers on a chip, and achieves directional laser emission through phased array technology. If this technology can succeed, it will completely overturn the existing mechanical Lidar completely solves the problem of low scanning speed of lidar. But like MEMS, phased array technology only solves the problem of green laser pointer emission, not the reception problem. So far, the maximum detection distance of phased array technology is still low. Most 5mW pen laser pointers have a button on the body. When you want to use the laser, you must press and hold the button. This is usually best for presentations where you will use the laser intermittently. For applications such as burning or bursting balloons, you need a device that can keep working without having to hold down the button. This is better for most applications, so look for a device with a "constant on/off switch".
