Abstract: PURPOSE:To increase a measuring accuracy by inclining either of the two surfaces of a light transmitting head, said two surfaces transmitting and reflecting coherent light, and forming a marginal side portion positioned in parallel to the other of the two surfaces on the side surface of the inclined surface. CONSTITUTION:The light emitted from a laser oscillator 4 is perpendicularly incident on a head 1 via a beam expander 5 and a beam splitter 6. The intensity of the interference fringes of the lights 3a, 3b and 3c reflected from the upper surface 9, the lower surface 8 both of the head 1 and a disk 2, respectively, is detected by using a TV camera 7. Thus, the surface 9 of the head 1 is inclined relative to the surface 8 and the marginal portion of the upper surface of the head 1 and the lights reflected from the surfaces 9, 8 and the disk 2 interfere with one another to produce the interference fringes. The position wherein the interference fringes are produced is changed by the distance (d) between the surface 8 and the disk 2. By obtaining the distance (x) between the end of the head 1 and a plane 9a-9b on which the interference fringes are produced by a predetermined expression, a gap (d) can be measured.
