摘要

为了研究航空低温温度对自准直检焦系统的影响，从而指导实际检焦系统的设计及修正，本文根据自准直检焦及几何光学原理，分析了单点成像、条纹成像及有无像散条件下，成像位置、成像宽度与接收的光强度差之间的相互关系，并给出了相关理论公式。结合实际的相机工况，对光学系统进行了相应的仿真，仿真结果显示，仿真双波峰电压值为1.4 V和0.47 V，与实际的检焦双波峰电压值1.38 V和0.56 V基本一致。根据结果进行了温控和柔性支撑，从而使检焦正常，提高了自准直检焦系统的温度适应性。本研究对系统的温度适应性具有指导作用。

Abstract

To analyze the influence of aeronautical low temperature on the self-collimation focus detection system

and enables the design and correction of the actual focus detection system

the relationship among various factors under different imaging conditions was investigated. Based on the principle of autocollimation focus detection and geometry

comparison of single-point and fringe imaging

imaging position and width according to different received light intensities

and presence and absence of astigmatic conditions were analyzed. Thus

a related analysis formula was deduced.Combined with the actual camera working conditions

the corresponding simulation of the optical system was performed

and the simulation results (simulated bimodal voltage values of 1.4 V and 0.47 V) were in accordance with the actual test data (peak-to-focus double-peak voltage values of 1.38 V and 0.56 V). The actual modification measures are carried out to improve the temperature adaptability of the self-collimation detection system.The temperature adaptability analysis is in accordance with the actual demand and has a guiding function for the temperature adaptability of the system.
