Abstract

The invention relates to a flash radar and a transmitting device and detection method thereof. The transmitting device comprises a laser device linear array, a galvanometer array and a driving module;multiple laser devices of the laser device linear array transmit exiting signals, and galvanometers which are correspondingly arranged on the exiting optical axes of the exiting signals transmitted by the lasers one by one are used for receiving and reflecting the exiting signals transmitted by the laser devices corresponding to the galvanometers; the driving module is used for driving the galvanometer array to vibration in a reciprocating manner in the preset angle range so as to control the exiting signals to be periodically transmitted to each target region in a target field of view, and the orderly scanning on the whole target region can be accomplished in one period. A VCSEL array is used as a light source, the beam quality is good, the space energy density is high, and the exiting signal can be once transmitted to each target region in the target field of view, the energy density of the target field of view vertical to a beam propagation direction is improved, the detection distance is increased, and the detection precision is improved.

Description

technical field [0001] The invention relates to the field of lidar detection, in particular to a flash radar, a transmitting device and a detection method thereof. Background technique [0002] At present, lidar has been widely used in many fields such as depth perception, mapping and ranging, tracking measurement, weapon guidance, atmospheric monitoring, traffic management, face or gesture recognition, robot obstacle avoidance, etc. According to different scanning methods, solid-state lidar is divided into three types based on micro-electro-mechanical system (Micro-Electro-Mechanical System, MEMS), phase-controlled vibration (Optical Phase Array, OPA) and flash (Flash). [0003] Flash lidar is often based on the principle of AM continuous wave ranging, that is, the light source "illuminates" the entire field of view at one time. However, the rapid attenuation of the output signal capability of the transmitter makes it impossible to achieve a long detection distance, especi...
