DEVICE CONTROLLING AEROPHOTOGRAPHY Russian patent published in 1999 - IPC

FIELD: photogrammetry, measurement technology. SUBSTANCE: invention is related to equipment meant to generate images especially intended for photogrammetry and photographing of terrain, it can be used in photocameras which shutters are controlled by pulses of electric current. Device includes photoelectric sensor, amplifier-former, frequency divider, five electron keys, three delay circuits, units controlling pressing table, indication, flip- flops, counting, master units and printing of service information, circuit expanding pulse duration, electronic switch, pulse generator, comparator, power amplifier, time relay, electric motor, seven decoders, four coincidence circuits, analog-to-digital converter, norming circuit, five division circuit, six multiplication circuits, four subtraction circuits, summing circuit and raising-to-power circuit. EFFECT: determination of resolving power of photographs in flight, facilitation of decoding and photogrammetrical processes, decreased time for obtainment of needed information, substantially reduced cost of these operations. 1 cl, 1 dwg
