AI Technical Summary

Technical Problem

Existing methods for processing dispersive interference fringes involve complex calibration processes in piecemeal space telescopes, resulting in high system costs, high complexity, and low reliability.

Method used

A channel spectral testing system based on point detectors is adopted. By combining a light source, a splicing primary mirror, an interferometer, a dispersive prism, a cylindrical lens, and a point detector array, calibration-free dispersive interference fringe processing is achieved. The point detector array is used for fitting and phase calculation. Combined with a microlens array and a beam splitter, the system complexity is reduced and the reliability is improved.

Benefits of technology

No dispersion interference fringe calibration is required, which significantly reduces system cost and complexity and improves system reliability.

Abstract

本发明属于光谱测试领域,尤其涉及一种基于点探测器的通道光谱测试系统及其测试方法,测试方法包括S1:光源向拼接主镜发出复合光;S2:复合光经拼接主镜的各子镜反射后进入干涉仪进行干涉形成干涉光;S3:干涉光依次经色散棱镜的色散、柱面透镜的压缩整形为线光斑并被点探测器阵列接收;S4:对色散干涉条纹进行拟合与相位解算,实现拼接主镜的共焦调节。本发明无需对色散干涉条纹进行标定,大幅度降低了系统造价和复杂度,并提高了系统可靠性。
