摘要
介绍了一种用小口径照明光管定标大口径红外光电系统的新方法。研制了现场红外辐射定标装置,其由辐射定标照明器件和红外辐射计组件(双波段1.40±0.02ΜM和4.50±0.04ΜM)两部分组成,并给出了它们的定标方法和定标结果及误差分析。实验表明,能满足大口径红外光电系统的定标要求。该装置体积小、重量轻,适合野外现场定标。
A new method to calibrate a large aperture infrared opto-electric system by using a small aperture illumination collimator is introduced in detail, A device for infrared radiometric calibration on the spot, including a radiometric calibration illumination element and an infrared radiometer （dual wave band 1.40±0.02 μm and 4.50±0.04 μm） ,was designed. The calibration method,results and the error analysis of the two parts are presented. It has been proved that the device satisfies all requirements of the large aperture infrared opto-electric system by experiments, Moreover, it has small volume and little weight, and it suits for the on-field calibration work well.
