Paper Abstract

In this paper, a synthetic performance evaluation system for infrared hybrid optical system is introduced, which contains blackbody lamp-house, collimator, exactitude three-dimensional moving device, integrating cavity, infrared detector and signal collecting and processing system. Performance test theories and methods of the system are presented in details. Knife-edge scanning is used for measuring point spread function (PSF) and optical transfer function (OTF), and equivalent lens substitution method is utilized to measure diffraction efficiency. The temperature stability of the system is researched by measuring its focus under different temperatures. The diffraction efficiency, PSF and OTF of a 3~5μm-wavelength infrared hybrid optical system are measured and compared to the results obtained from foreign OTF measuring instruments. The testing results show that the synthetic performance evaluation system of infrared hybrid optical system can not only precisely measured PSF and OTF, the traditional optical performance; but also complete testing of other performance, such as the diffraction efficiency and temperature stability.
