Abstract

The invention relates to a transmitting lens, an area array laser radar, and a movable platform. The transmitting lens comprises an optical shaping structure which is set in a light transmitting direction of a transmitting light source. The optical shaping structure comprises at least one cylindrical lens, and the length direction of a cylindrical projection disposed at one side, close to the transmitting light source, of the cylindrical lens is perpendicular to the divergent direction of a transmitting light beam. The transmitting light beam becomes a uniform light beam with a set divergenceangle and a set shape after passing through the optical shaping structure. The invention also provides the area array laser radar, and the laser radar comprises an area array light transmitting mechanism, an area array light receiving mechanism, and a main control board. The area array light transmitting mechanism comprises a transmitting light source, a drive transmitting circuit and the transmitting lens. The invention also provides the movable platform. The invention solves a problem that transmitted beams of a transmitting system of a conventional area array laser radar are not uniform, and the testing and operation safety and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a transmitting lens, an area array laser radar and a mobile platform. Background technique [0002] LiDAR (Light Detection and Ranging) is the abbreviation of light detection and ranging system. LiDAR is an active distance detection device that uses lasers or LEDs as the emission light source and photoelectric detection technology. Lidar is an advanced detection method combining laser technology and modern photoelectric detection technology. It is mainly composed of transmitting system, receiving system, information processing and other parts. The transmitting system includes various forms of lasers or LEDs; the receiving system uses receiving lenses and various forms of photodetectors. [0003] The commonly used transmitting modules in mechanical rotating lidar are line beams, which are then mechanically rotated to realize area array scanning. This puts high d...
