Abstract

The invention discloses a clamping device of three-beam speed-measuring laser radar collimators. The device consists of collimator installation members, a three-leg base and a connection rack, wherein the collimator installation members are key members which are used for fixing collimators, the collimators are fixed to the installation members through screws, the installation members are fixed to the three-leg base, the angle of the three collimator installation members which are fixed to the three-leg base can be adjusted, three collimators are arranged at certain angels, reverse extension lines of three collimators are intersected at one point, the three-leg base is a main body of the device and consists of three planes which are arranged at 120 degrees, the three-leg base provides the angel base and the support for the fixing of collimators, and the connection rack is used for fixing the device to a vehicle body through screws and bolts. Three collimators are fixed and arranged at certain angels, requirements of the demodulate algorithm can be met, the vibration error is reduced and the speed-measuring accuracy is improved.

Description

technical field [0001] The invention relates to a fixing device for a three-beam speed measuring laser radar collimator, which belongs to the field of Doppler laser speed measuring radar and mechanical design. Background technique [0002] Lidar is a radar with laser beams as the information carrier. LiDAR can not only measure distance accurately, but also measure speed accurately, track accurately and image with high resolution. Lidar has a wide range of applications and can be used in many fields such as military, aerospace and industrial production. [0003] Doppler speed measurement lidar is a kind of laser radar based on the optical Doppler effect, which can be used to measure the flow velocity of liquid and gas or the movement velocity of solid targets, and has a very wide range of applications in science and industrial technology. [0004] The Doppler speed measuring lidar adopts the active detection method. The system emits a laser with a certain waveform to irradi...
