GEAR MEASURING POSITION AND MOVEMENT OF OBJECT Russian patent published in 2003 - IPC

FIELD: measurement technology, linear movement pickups designed to measure position and movement of object. SUBSTANCE: gear has radiation source, capacitor, code scale meant for connection with object and so built in the form of line measure that linear distances between lines are not equal to one another, photosensitive elements, analog- to-digital processing and control unit which input is coupled to outputs of photosensitive elements. Gear is also fitted with channel counting single pulses that incorporate set in sequence radiation source, capacitor, grid on which raster is applied which length is greater than maximum interval between adjacent lines of scale and in which focus photodetector is positioned. Output of photodetector is connected to input of unit counting single pulses. EFFECT: widened functional potential related to provision for reliable operation at high speeds of movement and therefore possibility of operation in closed systems of automatic control over measurement process. 3 dwg
