TV DEVICE TO DETERMINE RANGE Russian patent published in 1997 - IPC

FIELD: optics. SUBSTANCE: invention is meant for use in measuring optico-electronic systems. TV device to determine range includes two TV pickups from which signals go to duration check selectors, coincidence circuits, comparison circuit and through delay line to input of flip-flop. Second input of the latter is coupled through counter and line decoder to synchronizer. Output signal of flip-flop is fed into two electron commutators to which signals from TV pickups are also supplied through amplitude and duration selectors. Outputs of electron commutators are connected to input of unit determining time mismatch which finds range. Interaction of units of device is ensured by operation of synchronizer. EFFECT: improved operational reliability. 4 dwg
