Installation and adjustment method of optical imaging system

Abstract

The invention discloses an installation and adjustment method of an optical imaging system. The optical imaging system comprises a mounting seat and an optical imaging device, the optical imaging device comprises a camera, a lens cone lens, a spectroscope and an objective lens. The method is used to complete the installation and adjustment of the optical imaging device based on a light source device and a collimating screen. The method comprises the steps of S1, adjusting the position and the angle of the light source device and the position and the angle of the camera so that the light source device emits light spots in the X direction and the emitted light spots vertically enter the camera for imaging, and the light spots have linear parts; and S2, installing the lens cone lens on the mounting seat, enabling the light spots emitted by the light source device to penetrate through the lens cone lens and then enter the camera for imaging, and adjusting the position and the angle of the lens cone lens so that the positions of the light spots in the camera can coincide with a first reference position. According to the invention, the adjustment precision can be improved, the operation is simple and fast, an adjustment speed can be improved, and the implementation cost is reduced.

Description

technical field [0001] The invention relates to a method for assembling and adjusting an optical imaging system. Background technique [0002] At present, the position accuracy and coaxiality of each component in the optical imaging system directly determine the imaging quality of the optical imaging system. Due to the functional integration of the optical imaging system, the number of internal lenses is increasing, and the difficulty of assembly and adjustment is getting higher and higher. If only relying on the outer circle of the lens for adjustment, although the operation is simple, the accuracy is low and the image quality is poor. The centering instrument can measure the center of curvature of the upper and lower surfaces of the lens, and then calculate the optical axis deviation of the lens by software, and then adjust the position. Although the centering instrument has high precision and can improve the accuracy of assembly and adjustment, the operation is complicat...
