Joseph P. Estrera,Edward J. Bender,Adriana Giordana,J. W. Glesener,Michael J. Iosue,Po-Ping Lin,Timothy W. Sinor +6 more
TL;DR: In this article, it is shown that it is possible to fabricate a long lifetime image intensifier with a single unfilmed microchannel plate and achieve improved imaging and performance characteristics.
Proceedings ArticleDOI
Modern night vision goggles for advanced infantry applications
TL;DR: The enhanced night vision goggle (ENVG) as mentioned in this paper was developed by Northrop Grumman Electro-Optical Systems (NGEOS) for the U.S. Army using an image intensifier and uncooled long wavelength infrared (LWIR) sensor.
Proceedings ArticleDOI
Extended blue GaAs image intensifiers
TL;DR: In this article, the role of the AlGaAs layer to the overall performance of the Gen III image tube was discussed with data presented on sealed tubes with quantum efficiencies greater than 20% at 500 nm.

Microchannel plate having an enhanced coating
TL;DR: In this article, an improved microchannel plate has been proposed to increase secondary electron production and prevent ions from leaving the micro-channel plate and damaging the photocathode, which has an input side and an output side.
