ABSTRACT:
The invention relates to a device for the optical recording of rapid proceses with a TV camera, which comprises means for deviating and suppressing the beam, in order to make the scanning beam run successively and cyclically over N lines of a picture plane on which the processes are projected.
A cyclic line counter (14) carries out one counting step for each line pulse and supplies a counting end pulse after p line pulses respectively, N/p being in integer >>1.
The end-of-count pulse is applied to the beam suppression circuit (13) of the TV camera (1) for the picture beam suppression and to a sawtooth generator (12), which controls the vertical deviation (4) of the beam.
