摘要
为了满足近年来国内飞速发展的红外测控的定标需求,设计出了一种能满足更宽大视场角以及更高分辨率红外探测系统的测控定标用黑体辐射源的测控系统。采用7075冷处理锻压合金制成该大型黑体辐射源的面本体黑体辐射面,其有效辐射面积达到1200 mm×1200 mm。对于该尺寸的大型黑体辐射源,国内并没有现成的测控控制方法与手段来验证其技术指标是否达到设计要求。根据大型黑体的主要技术指标要求,给出了黑体测控及控制方法,并通过实际测控取得的数据验证了黑体测控系统的准确性。
Abstract
To meet the calibration demands of infrared measurement and control developed rapidly in China in recent years, a measurement and control system for a large blackbody radiation source used for calibrating infrared detection systems with larger field-of-view angle and higher resolution is designed. The blackout radiation surface of the large blackbody radiation source is made of 7075 cold-treated forging alloy. Its effective radiation area reaches 1200 mm×1200 mm. For such a large blackbody radiation source, there are no any ready-made control methods and means which can verify whether its technical specifications meet the design requirements. According to the main technical specifications of the large blackbody, the measurement and control method is given. The accuracy of the blackbody measurement and control system is verified by the data obtained in actual measurement and control.
