New Technologies Are Gaining Attention Laser Pointer
Laser pointer radar. Historical review and prospects of East and West. Not long after lasers were invented in the 1960s, lidars have developed on a large scale. Lasers have become a real enabler, making lidars both cheap and reliable, making them more competitive than other sensor technologies. Lidar starts working in the visible region (ruby laser), then in the near infrared region, and finally in the infrared region (CO2 laser). At present, many lidars work in the near-infrared region (? 1.5 μm) which is harmless to the human eye. Based on the laser pointer radar principle. Many new technologies such as OCT and digital holography are gradually gaining attention.

Application
Laser pointer radar is mainly used for ranging. Positioning and graphic drawing of earth and extraterrestrial objects. Coherent lidar has important applications in environmental applications. For example, the development of wind sensing and synthetic aperture lidar; gated imaging is mainly used in military, medical and security aspects; laser micro radar has been applied in vascular research and ophthalmic vision correction. Ghost lidar has been applied in theory and simulation in the form of new technologies. Laser pointer radar is an important technology. Applications in autonomous vehicles and unmanned aerial vehicles.
