Abstract

The invention relates to an infinity position calibration system and method of an optical target simulation system. The calibration system comprises an illumination subsystem, a simulation target subsystem, a spectroscope, an imaging subsystem and a reflection loop subsystem, the simulation target subsystem comprises at least one simulation target; a simulation target illuminated by the illumination subsystem is divided into two light paths by the spectroscope, one light path generates a simulation image in the imaging subsystem, and the other light path generates an auto-collimation image in the imaging subsystem after being reflected by the reflection loop subsystem. The system and the method provided by the invention are used for calibrating the infinity position, so that a more accurate infinity position can be calibrated, and the influence of inaccuracy of infinity position calibration on a simulation effect is reduced.

Description

technical field [0001] The invention relates to the technical field of target characteristics and detection, in particular to an infinite distance position calibration method and system of an optical target simulation system. Background technique [0002] The finite distance target is simulated in the laboratory, and the quantitative defocusing method is often used for simulation. Before the target simulation, the infinity position calibration, that is, the calibration of the zero point position is required. The calibration of the infinity position is a very important task. No matter how accurate the sensitivity of the quantitative defocus is, once the zero position calibration is not accurate, it means that the target position is very different from the actual simulated position, especially near the zero position. [0003] The structure of an optical target simulation system is as follows: figure 1 As shown in , usually the positional relationship of the collimator, target...
