Abstract
PURPOSE: To make the displacement of a measured body proportional to the change in an output, by placing the light reception face of a position detector so that the face coincides with the loci of a light spot image on the measured body, which take place when the body is displaced.
CONSTITUTION: A light beam from a light source 1 is converged into a thin irradiated light beam 3 by an irradiation lens 2. The thin beam is projected to a measured body 4 in parallel with its displacement to be measured. Reflected light 3' from the body 4 is received by a condensing lens 5 in a direction different from that of proceeding of the beam 3 to form a light spot image on a light receiver 7 in a position detector 6. The receiver 7 is so placed that the loci of the light spot image coincide with the light reception face of the receiver. The ratio between both photoelectric (currents) i1, i2 of the light receiver changes depending on the position of the light spot image. The position y of the light spot image is determined by a calculator 8. The output of the calculator is applied to a compensation circuit 9 to perform compensation to make the displacement x of the body 4 and the output of the calculator 8 proportional to each other.
