DEVICE FOR AUTOMATED MEASUREMENT OF ANGULAR VALUES Russian patent published in 1998 - IPC

FIELD: measurement technology. SUBSTANCE: device has laser, mirror unit, photosensitive instrument made as linear photosensitive instrument 3 with charge coupling, and indication unit 18. Device also includes synchronous generator 4, amplifier 5, comparator 6, first counter 8, first trigger 9, delay line 10, first register 11, second register 12, second trigger 13, third trigger 14, OR gate 15, second counter 16, and computer unit 17. Interference picture projected on photosensitive zone of photosensitive instrument with charge coupling develops in analysis plane. It causes arrival of video signal at output of photosensitive instrument 3 with charge coupling. This signal corresponds to interference picture being projected. Video signal is converted to parallel digital code which carries information of object position. Value to be measured is calculated in computer unit 17, and measurement result is displayed by indicator. EFFECT: enhanced convenience of measurement result reading. 4 dwg , 2 tbl
