PULSE COORDINATE TRANSDUCER Russian patent published in 1997 - IPC

FIELD: determination of coordinates of pulse source of light, semiautomatic tracking of flying object by IR responder. SUBSTANCE: proposed transducer is part of device determining coordinates of pulse source of light. Transducer has objective lens in which focal plane coordinate photodetector is placed, source of cut-off voltage, summing-difference unit, four identical channels each including input transformer and operational amplifier with fixed gain factor. Starts of primary windings of input transformers are connected to proper outputs of coordinate photodetector and finishes - to source of cut-off voltage. Secondary windings of input transformers are connected to corresponding inputs of operational amplifiers. Outputs of channel operational amplifiers are connected to proper inputs of summing-difference unit that is built on three operational amplifiers and resistors of same nominal. Output signals of summing-difference unit are outputs of transducer for heading, pitching and summary signal. EFFECT: increased accuracy of determination of coordinates and diminished dimensions of transducer. 1 dwg
