Abstract: Three different types of image-converter cameras have been designed over the past several years with various characteristics but all emphasizing fast exposure rates. The three cameras all use the Mullard converter tube type 1201 with the short-persistence blue phosphor for photographic recording. The first camera produces a sequence of six rectangular images having an aspect ratio of about 5:1. The exposure time of 0.4 μsec was used and a fixed exposure interval of 5 μsec. This camera takes one group of six exposures at a time with a relatively long recovery time. The second camera has considerably advanced characteristics. This camera makes six exposures on a single frame at rates varying from 2 × 106 to 2 × 104 exposures/sec. The frame rate extends from zero to 5000, the upper limit depending on exposure rates. Exposure durations have these values: 0.1, 0.3, 1.0, 3.0 and 10.0 μsec. Repetition-rate and exposure-time duty cycle may not exceed 20%. Deflection of the image takes place on both axes, producing two rows of three exposures. The third and latest camera design is similar to the second, having exposures of 0.1, 0.3, 1.0, 3.0 and 10 μsec and corresponding exposure rates of 2 × 106 to 2 × 104 exposures/sec. The sequence pulse and shutter pulse generator is very similar; however, the sweep is wholly on one axis and therefore similar to that of the first camera described. The mechanism of sweep generation is quite different, however, the basic sweep form being generated by a diode-pump counting circuit. Displays of 4 or 8 images may be selected.
