【摘要】 采用美国 PI、Santa Barbara 红外和 Lumitron 的红外测试设备,进行系统集成,构建成了通用的红外测试系统。它既能完成1024×1024元以下任意像元数的中波红外和长波红外焦平面阵列性能参数的测试,又能完成中波红外和长波红外热像仪系统级性能参数的测试,具有很好的适用性及技术的先进性。中波红外热像仪的测试结果 NETD=15.8 mK,与 CEDIP 的结果15.13 mK 相差0.67 mK。测试精度为±1.49 mK。长波制冷红外焦平面阵列探测器的测试结果 NETD 为26.47 mK,与 Sofradir 的结果24.43 mK 相差2.04 mK,测试精度为±1.63 mK。更多还原

【Abstract】 PI-7700 of PI company,RTB-3000 of SBIR and SVS-2000D of Lumitron are integrated to be a universal infrared test system.It can test the MW and LW focal plane array detector and thermal imager whose pixel format is less than 1 024×1024.It is practical and has a lot advantages.The test result of the MW thermal imager is NETD=15.8 mK which is 0.67 mK larger than that of CEDIP(15.13 mK)and the test accuracy is±1.49 mK.The test result of the LW cooled focal plane array detector is NETD=26.47 mK which is 2.04 mK larger than that of Sofradir (24.43 mK)and the test accuracy is±1.63 mK.更多还原
