摘　　要：利用电子俘获材料的快速红外上转换特性，将其制成红外上转换屏与可见光阴极耦合构成了一种适用于条纹相机的新型组合红外阴极，测量表明：它能将可见光条纹相机的波长响应范围延伸至０．８～１．６μｍ，而且时间分辨率优于２４ｐｓ、红外最小可探测能量密度优于４．８×１０－９Ｊ／ｍｍ２．Using the characteristics of electron trapping material (ETM) for the rapid infrared upconversion, a kind of novel combined infrared photocathode was made by coupling ETM based infrared upconversion screen with visible photocathode. The present experiment showed that the combined photocathode is able to extend spectral sensitivity to 0.8￣1.6μm and make time resolution better than 24ps, and minimum detectable energy density less than 4.8×10 9 J/mm 2.
