Abstract: PURPOSE:To enable accurate measurement of a distance to a substance to be measured, by a method wherein a light-sensing means, such as a line sensor, which senses a reflected light is rotated around the axis of projection by a rotating means. CONSTITUTION:A light emitted from a semiconductor laser 1 is condensed as a light spot by a projecting lens 2 and this condensed light is applied onto the surface of a sample 8. A scattered light formed by reflection of this light is condensed by a light-sensing lens 4 and the intensity of the sensed light and the light-sensing position are detected by a line sensor 5. A controller 9 controls a motor 7 for rotating a light-sensing unit 6 around the axis of projection, through a rotating motor control circuit 10.
