摘要
PROBLEM TO BE SOLVED: To provide an optical apparatus for quantitatively detecting linear motion and rotational motion, which can be easily manufactured on a detector side.;SOLUTION: Luminous fluxes of two light emitters 11, 12 transmit through a translucent region 21 and a non-translucent region 22 provided on a raster board which projects motion of the optical apparatus for quantitatively detecting linear motion or rotational motion, and the transmitting light is shed to an individual light receiver 3. The light emitters 11, 12 are controlled by pulse operation, and pulses are separated from each other in an evaluation circuit connected with the light receiver 3.;COPYRIGHT: (C)2000,JPO
