Optical imaging system

Abstract

The invention discloses an optical imaging system. The optical imaging system comprises a casing, wherein a camera is fixedly mounted in the casing; a lens is arranged at the top of the camera; a glass protecting cover is arranged in the position, corresponding to the lens, of the top of the casing; a first fixed rod is fixedly connected with the surface of the inner wall of the glass protecting cover; a second fixed rod is fixedly connected with the surface of the inner wall of the glass protecting cover and located on the right side of the first fixed rod; a first connecting rod and a secondconnecting rod are fixedly connected between the first fixed rod and the second fixed rod; a first reflecting mirror is rotationally connected with the surface of the first fixed rod; a second reflecting mirror is rotationally connected with the surface of the second fixed rod. According to the optical imaging system, under the cooperation of the first reflecting mirror, the second reflecting mirror, a third reflecting mirror, a fourth reflecting mirror, a convex lens and electric drive pushers, the problem that a large view field range of an optical imaging lens is realized by rotating the angle of a prism reflecting surface, but the viewing angle of an existing camera cannot be effectively expanded is solved.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical imaging system. Background technique [0002] As imaging lenses are more and more widely used in monitoring, security, vehicle, projection, special environment detection, monitoring and biomedical detection, the application of large field of view and large angle range optical imaging lenses will also be a development trend . However, as far as the current technology and engineering process are concerned, it is still difficult to achieve ultra-large field of view and large-angle imaging. On the one hand, in terms of design, large-angle imaging will produce large distortion, because when the viewing angle is greater than 120°, the distortion will appear The rapid growth makes the imaged image seriously distorted, the aberration is difficult to correct, and the large-angle imaging system is easy to make mistakes in the software design of light; on the other hand,...
