ABSTRACT:
A photographic exposure meter in visualization equipment for detecting the presence or absence of a pulse of laser light on a target. Light from a laser pulse which forms a hologram, is scattered when it impinges on the target plate and detected by a photodetector, the resultant pulse signal being integrated and amplified. The output pulse, proportional to the hologram exposure, is fed to a storage oscilloscope for convenient display.
