Lidar lens

Transmitting and receiving systems are vital parts of a lidar system.
According to the characteristics of an all-fiber lidar, the aspherical lenses and optical circulators are utilized to optimize the laser emission and reception of optical system. By adopting a co-propagating optical path system, the laser echo is reflected and received by the original system and it reaches the detector through the fiber circulator. This design not only enables the detection and reception of reflected signals over long distances but possesses the advantages of small size, low cost, and relatively simple design structure.
