Paper Abstract

The output brightness temporal response of non-gated image intensifying systems was examined. Generation III gallium arsenide image intensifiers (image tubes) using the P43 and P20 phosphors were tested for image persistence, minimum event detection, and minimum event temporal separation (multiple burst testing, where "event" refers to a burst of light of determined duration and brightness). Persistence tests showed some correlation with previously published data and suggest that both phosphors (P43 and P20) display multiple stages of decay. The minimum event detection tests showed the Generation III Image Intensifier tubes capable of detecting pulses with durations in the low microsecond region and suggested that for faster test setups the tubes may have the capability to operate in the nanosecond region. Finally, the multiple burst testing shows the complex temporal nature of image tube power supplies when encountering multiple, rapid flashes of light.
