ABSTRACT:
Using a conventional camera tube, a streak image of light pulse formed on a streaking image tube is converted into an electronic signal, progressively scanned, without interlaced scanning, using scanning lines n-times as many as in standard scanning, and stored in a picture memory unit. The memorized picture is read out as video signals by a 2n:1 interlaced scanning. The video signals are sent to an integrating unit for integration by scanning line. Each integrated value is stored at an address corresponding to the order of the scanning line in a second memory. When the integrated values for all scanning lines have been memorized, they are read out in the order of address to produce a waveform corresponding to the streak image. Also, on completion of the storing in the second memory, the video signals read out from the picture memory unit by the 2n:1 interlaced scanning and signals obtained by converting the integrated values read out from the second memory by the 2n:1 interlaced scanning into time modulation pulses are superimposed on the screen of the television monitor to clarify the relation between the streak image and a waveform showing its intensity distribution.
