Multiple-Exposure Image-Intensifier Camera

摘要

An image-intensifier camera with light gain of a few thousand times and exposure pulse times as short as 8 ns has been applied to the study of high explosives. A unique feature is the recording of the self-light of detonating explosive, which appears as a line in the photograph, with up to ten multiple exposures independently spaced in time. The light gain of the intensifier allows recording detonation light with very short exposures even when the light is very weak, too weak for ordinary photography. (ERA citation 01:024375)
