Simulation method of an active optical system of an optical remote sensing camera

Abstract

The embodiment of the invention discloses a simulation method of an active optical system of an optical remote sensing camera, The active optical system simulation method integrates optical, mechanical and control disciplines, involving the optical structure of the camera, six-degree-of-freedom active optical actuator, wavefront sensing algorithm, correction algorithm and error term simulation model. Based on this simulation model, global optimization is easier to obtain the global optimal solution than single disciplinary optimization. The embodiment effectively solves the problem that the existing active optical simulation method adopts a single subject and an idealized model, which leads to large error and is difficult to simulate the actual active optical correction process.

Description

technical field [0001] The invention relates to the technical field of integrated simulation of an optical remote sensing camera, in particular to a simulation method for an active optical system of an optical remote sensing camera. Background technique [0002] Optical remote sensing cameras are widely used in resource detection, land survey, astronomical observation and other fields, and have played an important role in economic and social development and scientific research. At present, the technical development trend of optical remote sensing cameras is towards large aperture, large field of view, and high resolution. The corresponding processing, manufacturing, support, and assembly are more difficult. , gravity environment, temperature and other factors, thus affecting the observation performance. [0003] At present, there are two methods used to improve the observation performance of optical remote sensing cameras: one is passive optics and the other is active optic...
