摘要
介绍了一种采用组合红外阴极和静电聚焦电子光学系统的新型红外扫描变像管.组合红外阴极是利用电子俘获材料的快速红外上转换特性,并将其制成红外上转换屏与可见光阴极耦合构成的.这种新型红外扫描变像管的波长响应范围可延伸至800～1600 nm,转换效率的峰值波长为1165 nm,时间分辨率优于15 ps.
Abstract
A novel infrared-sensitive streak image tube with a combined infrared photocathode and electrostatics focused electronic optical system is described. Using the characteristics of electron trapping material(ETM) for the rapid infrared up-conversion, a kind of combined infrared photocathode is made by coupling ETM-based infrared up-conversion screen with visible photocathode. The novel infrared-sensitive streak image tube is able to extend spectral sensitivity to 800～1600 nm.The peak value of the converting efficiency is located at 1165 nm. Time resolution is superior to 15 ps.
