DEVICE FOR PROCESSING OF SIGNALS OF PULSE COORDINATE PICKUP Russian patent published in 1998 - IPC

FIELD: determination of coordinates of pulse light source. SUBSTANCE: device has sum channel, identical heading and pitch control channels, as well as strobe forming unit the input of which is supplied with synchronizing pulses, and output is connected to control input of sum channel electronic switch. Sum channel includes automatic gain control unit having series-connected controlled amplifier, electronic switch and peak detector, as well as reference-signal forming unit the output of which is connected to control inputs of electronic switches of heading and pitch channels. Heading and pitch control channels includes series-connected controlled amplifier, electronic switch and peak detector. Output of peak detectors are heading and pitch outputs of device. Gain is controlled in three channels by summary signal. Controlled amplifiers are made in the form of series-connected controlled attenuator and pulse amplifier. Signal inputs of controlled attenuators serve as device inputs, and control inputs of attenuators are connected to output of unit of sum channel automatic control. Reference-signal forming unit has series-connected comparator with threshold input and univibrator. Threshold input of comparator is connected to electronic switch output of sum channel, and univibrator output serves as output of reference-signal forming unit. EFFECT: higher accuracy of coordinate measurement, reduced overall dimensions. 3 dwg
