Abstract

The embodiment of the invention discloses a method for simulating the dynamic ellipticity of imaging by an optical remote sensing camera. The simulation method can be summarized as four steps: integrated simulation analysis of micro-vibration in time domain, integrated simulation analysis of precise image stabilization, linear superposition of point spread function (PSF) and calculation of ellipticity of point spread function (PSF). This simulation method integrates the three disciplines of optics, mechanics, and control, and can comprehensively consider the coupling effects between different disciplines, which is closer to the real working process of optical remote sensing cameras. The evaluation of optical system imaging performance has stronger guiding significance.

Description

technical field [0001] The invention relates to the technical field of optical remote sensing imaging, in particular to a simulation method for imaging dynamic ellipticity of an optical remote sensing camera. Background technique [0002] With the increasing demand for astronomical observation and military and civilian earth observation, optical remote sensing cameras are developing in the direction of large aperture, large field of view and high image quality. In order to ensure that the imaging quality of the optical remote sensing camera meets the index requirements in the working state, considering that the optical remote sensing camera often has the characteristics of long working time and long exposure time, it is necessary to consider that when the structure of the optical remote sensing camera is disturbed by various environments within a certain period of time, the optical System imaging performance. At present, dynamic ellipticity analysis is a good evaluation met...
