Research of Calibration Technology of InterferenceHyperspectral Imager on Secondary Planet
干涉型超光谱成像仪的星上定标技术研究

This paper presents research of several calibration methods on secondary planet, according toprinciple and characteristic of the Interference Super-spectral Imager, and requirement of calibration onsecondary planet. A method of Calibration based at first image plane makes use of two ends of narrow slitor a hole beside it to introduce the calibration light. There are two methods of converging calibration light,one is using convergent lens, the others self-focus lens. In method of whole system calibration, calibrationlight can be introduced by rotating the mirror 90 degree. Lambert reflector or integral sphere can be usedin this calibration. Place Nd-in glass in optical circuit can achieve both radiometric calibration and spectralcalibration. In actual, Analyzing the structure and characteristic, according to optic design and realizationpossibility of structure, a method of integral sphere used in calibration is chosen. By contrast, acalibration method of using integral sphere has compact structure and large energy, can be used to achievethe calibration of total system, aperture, and part viewing field.
