ELECTROSTATIC GYRO WITH OPTICAL READING OF POSITION OF AXIS OF ROTOR Russian patent published in 1998 - IPC

FIELD: gyroscopes. SUBSTANCE: increased accuracy and reliability of electrostatic gyro with optoelectron system of reading of angular information are achieved by elimination of uncertainty in reading of angular information by generation of signals of reference ( coarse ) reading by optoelectron means. With this in mind distances between contrast lines on rotor of gyro are made of different width and each meter of phase shift is composed of two units of phase automatic tuning, two single-shot multivibrators, two logic AND circuits, counter, two counters with initial setting, two phase-to-code converters and flip-flop. EFFECT: increased accuracy and reliability of electrostatic gyro. 2 dwg
