Optical system

Abstract

The invention relates to the field of laser optical design, and provides an optical system. The optical system comprises a dichroscope, an image receiving unit and a laser emission unit. The image receiving unit is used for receiving target range object reflected light which is reflected by the dichroscope and is provided with preset wavelength, and forming and outputting image information so as to acquire position information of a target object. The laser emission unit is used for carrying out laser emission on the target object through the dichroscope according to the position information of the target object. The laser emission optical axis of the laser emission unit is coaxial with the reflected light receiving optical axis of the target range object reflected light. According to the embodiment of the invention, through the design that the laser emission optical axis of the laser emission unit is coaxial with the reflected light receiving optical axis of the target range object reflected light, the real-time striking accuracy and reliability of the optical system are improved; and meanwhile, through a design of a transceiving coaxial system, the structure of the device is quite simple, the size is small and design and manufacturing cost of a laser radar is reduced.

Description

technical field [0001] The invention belongs to the field of laser optical design, and in particular relates to an optical system. Background technique [0002] With the development of science and technology, small target capture and attack equipment are becoming more and more intelligent, such as laser mosquito killer device, which includes a target detection module, which is used to scan and detect targets in the field of view with a cmos camera, and obtain The coordinate information of the target under the detection light path; the target strike module is used to use the coordinate information to control the strike beam to strike the target in real time. [0003] However, in the small target capture and striking device in the prior art, the optical path of its target detection module and the optical path of the striking light beam of the target strike module are on different optical paths, so that the optical system of the whole device can capture and strike the target ac...
