TELEVISION-CORRELATION RANGE FINDER Russian patent published in 1997 - IPC

FIELD: photo, movie and TV equipment. SUBSTANCE: the range finder uses digital comparators, scanning unit, flip-flop, AND gate; the computing unit is made in the form of a series-connected permanent storage and a register; the correlator is built around a differential circuit, its first and second outputs are connected to the first like inputs, and the third output - to the other like inputs of the digital comparators, whose outputs are connected to the inputs of the AND gate, the output of the latter is connected to the first input of the permanent storage, connected to whose second input and the first input of the scanning unit is the range scanning input, and the output is connected to the register input; the sync generator outputs are connected to the second and third inputs of the scanning unit, the line-frequency output is additionally connected to the inputs of the AND gate and first input of the flip-flop, the first and second outputs of the scanning unit are connected to the respective inputs of the TV cameras, the third output is connected to the second input of the flip-flop, and the flip-flop output is connected to the respective input of the correlator. EFFECT: improved design. 3 dwg
