Abstract

A compact camera system, made up of an IR sensitive phosphor activated by a photographic flashgun and with Polaroid film recording, has been developed for use in laser beam diagnostics at 1.315 μm. Detection thresholds, phosphor camera sensitivity, linearity, saturation, and time response have been determined. Estimates are made of the performance of a phosphor combined with an electronic system based on silicon vidicons or photodiode arrays.
