Optical aiming system, camera module and electronic equipment

Abstract

The invention relates to the technical field of optics, in particular to an optical aiming system, a camera module and electronic equipment. The optical aiming system comprises a diaphragm and a plurality of lens combinations. The beneficial effects of the invention are that: the optical aiming system has the advantages that the optical aiming system is long in aiming distance, high in measurementprecision and large in field angle, high-precision measurement of the aiming distance within the range from 0.5 m to 100 m can be achieved, the half field angle can reach 16 degrees, dispersion spotsunder all the field angles and all the aiming distances are uniform, roundness is good, and chromatic aberration and aberration are small; and (2) the structure is small and compact, a non-glued separated structure is adopted, the system comprises five lenses, the total length of the system is less than 20mm, and the maximum clear aperture is less than 10mm.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to an optical aiming system, a camera module and electronic equipment. Background technique [0002] In scenarios where the machine is associated or interferes with other things during dynamic operation, such as aerial refueling of aircraft, rendezvous and docking of underwater unmanned aerial vehicles, rendezvous and docking of spacecraft, automatic loading and unloading of large robots, etc., it is necessary to accurately capture the attitude of the other party in advance Information for machine drivers to provide decision-making reference for rendezvous and docking.

Problems solved by technology

[0003] The optical system composed of optical elements such as lenses and diaphragms in sequence can be used for imaging or other optical information processing. When the traditional optical system is used for gesture capture in the above-mentioned specific scenes, there are often problems that cannot be captured at a long distance and cannot be captured at a short distance. Therefore, it is necessary to develop an optical system with a larger field of view and higher aiming accuracy to meet the needs of attitude capture in fast-moving scenes
