为了实现快速、准确地校准机载多光谱光电跟踪设备中多光轴的一致性，设计一种基于卡塞格林式的光轴一致性校准系统。该系统使用卤素灯作为可见光光源，黑体作为红外光源，ZnS玻璃为基底的星点分划板提供无穷远目标，系统通光孔径为200 mm，焦距为1 500 mm，轴上点出射光平行性优于10，满足多光谱多光轴的一致性检测中1的要求。
Abstract
To calibrate the optical axis consistence of airborne multi-spectral and multi-axial optoelectronic tracking device fast and accurately, a calibration system for the consistence of optical axis based on Cassegrain optical system was designed. This system used halogen lights as the visible light source, blackbody as the infrared light source, and ZnS reticle was adopted to provide infinite object. The aperture of the system was 200 mm, and the focal length was 1 500 mm. The emergent beam parallelism of points on the axis was better than 10, satisfying the demand of 1 in the test of consistence of multi-optical axis and multi-spectrum system.
