Abstract
Abstract An electrooptical camera comprises an image intensifier connected to a control system for gate and scanning, which system includes a serial arrangement of a trigger oscillator, a master oscillator and an amplifier unit, which comprises preamplifiers and output amplifiers for the gate and scanning channels. The trigger oscillator is a relaxation oscillator utilizing an avalanche transistor and a storage capacitor in its collector circuit. The master oscillator is a Marx oscillator with an optical input and with cable line timing sections of different lengths in its collector circuits. The output amplifier of the gate channel is coupled to the gate system of the image intensifier. The output amplifier of the scanning channel is electrically coupled, via integrators, to a load in the form of a wide-band two-channel cable transformer/shaper, which is coupled to the deflection system of the image intensifier. The integrators utilize RLC-elements and can be inserted between the output amplifier of the scanning channel and its load, via a scanning time selector which includes sealed terminals.
