Embodiment Construction

[0032] In order to make the objectives, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0033] figure 1 A schematic structural diagram of a lidar transmitting system provided for an embodiment. The system 100 includes: a transmitting end optical unit 110 , a fast axis collimator (FAC for short) array 120 and a laser diode LD transmitting array 130 . Correction of the axis direction. When the laser beam emitted by the LD emitting array 130 passes through the FAC array 120 , the divergence angle of the laser beam in the direction of the fast axis is corrected, and then the laser beam is emitted through the emitting end optical unit 110 .

Abstract

The present application relates to a laser radar transmitting system, comprising: a transmitting end optical unit, a fast-axis collimation FAC array and a laser diode LD transmitting array, the FAC array is used to fast-axis the laser beam emitted by the LD transmitting array Direction correction: when the laser beam emitted by the LD emission array passes through the FAC array, the divergence angle of the fast axis direction of the laser beam is corrected, and then emitted through the optical unit at the emission end. Using the laser radar launch system, its volume is greatly reduced, and its cost is also greatly reduced.

Description

technical field [0001] The present application relates to the field of optical technology, and in particular, to a laser radar transmitting system. Background technique [0002] With the rapid development of optical technology and communication technology, lidar technology has developed rapidly. Lidar is widely used in target detection and other fields because it can detect the position and velocity of the target object by emitting laser beams and receiving the laser beams reflected back from the target object. [0003] At present, in order to make the laser beam emitted by the lidar launch more efficiently and reduce the energy loss, the common practice is to expand the diameter of the transmitting end or increase the focal length of the transmitting system to achieve higher energy utilization. [0004] However, by enlarging the diameter of the transmitting port or increasing the focal length of the transmitting system, the cost is high, the volume is large, and it is inco...
