LIDAR - Light Detecting and Ranging

Lidar is a radar system which consists of laser emitting device, telescope collection device and signal analyzing device. As one of the active remote sensing technologies, lidar has been applied in many areas such as terrestrial vegetation monitoring, atmospheric laser transmission, global climate prediction and monitoring of the marine environment. With the development of laser technology and optical monitoring technology, the lidar achieve high accuracy, high spatial resolution remote sensing probe by foundation, car, airborne and spaceborne.

Changchun New Industries (CNI), founded in 1996, is a manufacturer of solid-state and diode laser systems. CNI laser features with high performance, nice reliability, and specifically designed for OEM, scientific, industrial and instrumentation use. In addition, CNI lasers are ISO-9001, FDA, CE, RoHS and JQA certified. CNI laser has the superiority in the stability and reliability, which can satisfy the customer’s demands of high efficiency and stability in different environments. CNI has provided lasers to many customers at home and abroad as laser light source in the laser radar systems.

Applications of CNI laser in Lidar

1. System of detecting Aerosol



    The absorption and scattering of Aerosols to sunlight will
change the atmosphere system. Aerosol testing provides important
data to the study of global 
warming and pollution of the environment.
      CNI provides lasers for the system of detecting Aerosol based
 on Mie scattering theory.



2. System of detecting the atmospheric temperature


      Detection of atmospheric temperature is important to the analysis
of weather forecasting, atmospheric environment and process of

atmospheric dynamics. At present, the method of measuring middle
atmosphere temperature is rare, so observing stratospheric temperature

by lidar is very effective. 

      CNI provides lasers for detection system of the atmospheric 
temperature based on Rayleigh scattering theory.
