Optical imaging system and method for adjusting imaging parameters through programming

Abstract

The invention discloses an optical imaging system and method for adjusting imaging parameters through programming. The system comprises a computer, an environmental factor generator, and a light-transmitting component. The optical parameters of the light-transmitting component meeting the imaging requirements are acquired, and computer programming is carried out according to the corresponding relationship between the optical parameters and the environmental factors to generate a control program of the environmental factor generator. When imaging is carried out, light emitted by a light-emitting component is imaged on an image plane through the light-transmitting component, the computer controls the environmental factor generator through the control program, and the environmental factor generator adjusts the environmental factors of the light-transmitting component, so that optical parameters of the light-transmitting component meet the imaging requirements. In the implementation process, the method can be repeatedly used in various imaging systems with different requirements only by importing corresponding programs, and the processing difficulty and the processing cost are effectively reduced on the premise that the imaging requirements are met.

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to an optical imaging system and method for adjusting imaging parameters by programming. Background technique [0002] In the field of imaging, the aberrations of the optical system mainly include seven types, namely spherical aberration, coma, astigmatism, field curvature, distortion, axial chromatic aberration, and vertical axis chromatic aberration. Due to the existence of these aberrations, they greatly affect the The imaging effect makes the image of the captured object blurred. Since the first telescope made by Galileo, scientists mainly considered how to effectively reduce the magnification when designing the imaging device. The above seven aberrations. The reason for the existence of the above aberrations is mainly because the current optical materials and the curvature surface processing ability of the material surface cannot perfectly eliminate the tolerance.

AI Technical Summary

Problems solved by technology

The existing imaging optical system mainly relies on multiple lenses, multiple materials, multiple radii of curvature, and multiple surface shapes, and then cooperates with the distance between various optical elements to minimize aberrations. In this A certain aberration, such as spherical aberration, can be eliminated by introducing a free-form surface or a multi-order aspheric surface in the process, but other aberrations cannot be perfectly eliminated

Moreover, the existing optical system is mainly composed of lens groups made of various materials. The number of optical elements is often relatively large, which occupies a relatively large space, and the processing and assembly tolerances are relatively strict, resulting in difficult production and high processing costs.
