Paper Abstract

A camera for surveillance purposes uses a microchannel-plate intensifier tube and motorised film transport system in a design which permits direct viewing of the intensifier screen via a biocular magnifier, combined with photography by direct contact of film on the fibre-optic output plate of the intensifier. Automatic gain circuits compensate for both subject brightness and exposure duration, so that correct exposure of the film is obtained without manual adjustment. Exposures from 1/10th to 1/3,000th sec. are available. A camera for projectile photography makes use of a system of multiple pulse gating of the microchannel-plate inten-sifier tube. The multiple gating enables high cut-off ratio ( 107) to be obtained. Exposure duration can be set from 100 ns to 10 us.
