Description

Technical Field

[0001] The utility model relates to the technical field of radar equipment, and more specifically, to a laser radar receiving backplane. Background Art

[0002] LiDAR is an abbreviation for Light Detection and Ranging technology. It measures information such as the distance, speed, and shape of a target object by emitting a laser beam and receiving the light signal reflected from the target object. In a LiDAR system, the receiving mirror backplane is an important component. It supports the mirror and ensures that the mirror can reflect the laser beam at a predetermined angle and direction, thereby achieving precise measurement of the target object.

[0003] Traditional LiDAR receiving backplanes adopt fixed installation or limited manual adjustment methods. This method can meet the requirements in static or minimally changing environments, but in dynamic, complex, or high-precision measurement scenarios, its limitations become apparent. The fixed-mounted backplane cannot flexibly adjust the angle of the mirror according to actual needs, resulting in a decrease in measurement accuracy or omission of target information. Although manual adjustment can improve this problem to a certain extent, it is cumbersome to operate, inefficient, and difficult to ensure the accuracy and stability of the adjustment.
