What is Lidar (LiDAR)? Lidar combines radar ranging capabilities with camera angular resolution to provide accurate depth-aware sensing to complete the image

Since Maman first obtained laser pulse output in 1960, the process of human compression of laser pulse width can be roughly divided into three stages: Q-switching technology stage, mode-locking technology stage, and chirped pulse amplification technology stage. Chirped pulse amplification (CPA) is a new technology developed to overcome the self-focusing effect generated by solid-state laser materials during femtosecond laser amplification. It first provides ultra-short pulses generated by mode-locked lasers. "Positive chirp", expand the pulse width to picoseconds or even nanoseconds for amplification, and then use the chirp compensation (negative chirp) method to compress the pulse width after obtaining sufficient energy amplification. The development of femtosecond lasers is of great significance.

A device that converts the CO concentration variable in the air into a corresponding output signal.

Narrow linewidth lasers are widely used as light sources and receivers in fiber optic communication systems. In terms of light sources, narrow linewidth lasers can provide high-quality and highly stable optical signals, which can reduce signal distortion and bit error rates. In terms of receivers, narrow linewidth lasers can provide high sensitivity and high-precision light detection, which can enhance the signal detection capabilities of the receiver. In addition, narrow linewidth lasers can be used for functions such as optical filtering and frequency conversion.

The wavelength of the 10G conventional SFP+ DWDM optical module is fixed, while the 10G SFP+ DWDM Tunable optical module can be configured to output different DWDM wavelengths. The wavelength tunable optical module has the characteristics of flexible selection of the working wavelength. In the optical fiber communication wavelength division multiplexing system, Optical add/drop multiplexers and optical cross-connects, optical switching equipment, light source spare parts and other applications have great practical value. Wavelength tunable 10G SFP+ DWDM optical modules are more expensive than conventional 10G SFP+ DWDM optical modules, but they are also more flexible in use.

Lidar (Laser Radar) is a radar system that emits a laser beam to detect the position and speed of a target. Its working principle is to send a detection signal (laser beam) to the target, and then compare the received signal (target echo) reflected from the target with the transmitted signal, and after proper processing, you can obtain relevant information about the target, 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.
