FIELD: information and measurement technology. SUBSTANCE: movement-to-code converter includes radiator 1, modulator 2, collimator 3, analyzer 4, generator 5, motor 6, former 7 of start of counting, amplifier 8, demodulator 9, filter 10, distributed photodetector 11, matching unit 12, processing unit 13 and unit 14 of control over motor with proper couplings. Analyzer presents opaque disc with radius R+ΔR with transparent zone of radius R inside which there are two opaque sectors - rectilinear 15 and spiral-shaped 16 mounted for light scattering. Distributed photodetector 11 is used to pick up information from analyzer 4. EFFECT: enhanced reliability and simplified design. 5 dwg
