ろの角変位測定装置。Two pairs (or one pair each) of a light source and a light receiving element are arranged between one (or two) slit disks fixed to a rotating shaft. In an angular displacement measurement device that converts an angular displacement caused between two slit disks (or between two slit disks) into a phase difference between the outputs of two light-receiving elements, each light source is a pulse lighting light source, and the period of its lighting control signal is are the same, the lighting control widths are different, and a logic circuit forms an AND output of the inverted output of the light receiving element facing the light source with the large lighting width and the output of the other light receiving element. Angular displacement measuring device.
