Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0034] see figure 1 As shown, the embodiment of the present application is a laser radar, which includes: a transmitting system 11 , an information processing system 12 and a receiving system 10 . Please refer to the receiving system 10 figure 2 shown, including optical system 101 and the following Figure 3-Figure 4 The receiving device 100 introduced in the embodiment. When the laser radar detects the information of the target object, the transmitting system 11 first emits a beam of laser light to the target object. After the laser light is reflected on the target ob...

Abstract

The invention relates to a receiving device, a receiving system and a laser radar. The receiving device includes: a liquid crystal optical switch and a receiving component, wherein the liquid crystaloptical switch includes a plurality of liquid crystal switches; the liquid crystal optical switch is disposed in front of the receiving component along a receiving optical path; and each liquid crystal switch in the liquid crystal optical switch is correspond to different laser signal emission angles for isolating reflection laser signals from non-target objects, so as to cause the reflection laser signals of the target objects to enter the receiving component. Through the receiving device, the receiving resolution of the receiving device can be improved, and at the same time, the anti-interference capability of the laser radar is improved.

Description

technical field [0001] The invention relates to the technical field of laser radar, in particular to a receiving device, a receiving system and laser radar. Background technique [0002] Lidar is generally composed of a transmitting system, a receiving system, and an information processing system. Among them, the transmitting system is used to transmit laser signals to the target, and the receiving system is used to receive the reflected laser signals on the target, which mainly includes the optical system and receiving devices, and the information processing system is mainly used to process the received laser signals to process. [0003] Traditionally, when laser radar is used to detect the information of the target object, the transmitting system emits a laser beam to the target object. After the laser is reflected on the material, a reflected signal will be generated. The reflected signal is received by the optical system and receiving system of the receiving system. Th...
