Problems solved by technology

It is impossible to reduce the overall volume of the laser radar without solving the problem in terms of the volume of the transmitting lens 12P and the receiving lens 22P
[0005] In addition, complex lens sets will bring high cost investment in both R&D and manufacturing
The yield rate of the overall equipment cannot be effectively controlled
Moreover, when the transmitting end 10P and the receiving end 20P are manufactured and installed separately, the relative position and matching degree require extra effort, which is inconvenient for production and use.

Abstract

The invention provides a single-layer chip type laser radar device. The device comprises a transmitting module, a receiving module and a processing module, wherein the transmitting module provides laser light to a preset range; the receiving module senses reflected laser rays from a preset range to be measured and calculated by the processing module; the transmitting module comprises a light source device and a transmitting lens, and the transmitting lens is of a single-layer type, so that the distance between the light source device and the transmitting lens determines the length of the single-layer chip type laser radar equipment. In addition, the invention provides a method of manufacturing the single-layer chip type laser radar device.

Description

technical field [0001] The invention relates to the fields of radar detection and laser radar, in particular to a single-layer laser radar device and a manufacturing and assembling method. Background technique [0002] LiDAR uses laser emission and reflection to detect target objects within the range. The efficiency of simple and common laser emission and reception is very low, and a complex optical system is needed to supplement the functions of emission and reception. Moreover, usually both ends need to be strengthened at the same time, otherwise it is easy to cause inaccurate judgment in post-processing. If the requirements for the emission and reception of light are not met, then no matter how good the algorithm processing is, the detection result cannot be accurately judged. [0003] Existing lidar devices such as figure 1 As shown, it mainly includes a transmitting end 10P and a receiving end 20P. The emitting end 10P further includes a laser light source 11P and a...
