Filed: 1988-09-22
Abstract: PURPOSE:To highly accurately detect the moving state of a mobile object by providing a pattern for measurement on the surface of a transparent scale plate, on which the cross section of incident luminous flux becomes smaller. CONSTITUTION:A luminous flux emitted from a laser 1 is made incident on a polarization beam splitter 3 after the luminous flux is condensed 2 and divided into a reflected and transmissive luminous fluxes of linearly polarized rays of light having equal light quantities.

Then the diffracted rays of light of a specific number of order of the transmissive diffracted rays of light made incident on and diffracted at the grating 7 are reflected 8 and again made incident on the position M1 after the rays of light are led through the same optical path in the opposite direction. The re- diffracted rays of light of the specific number of order by means of the grating 7 are changed to linearly polarized rays of light having a polarized azimuth different from that of the rays of light made incident on the grating 7 through the wave plate 4 and made incident on the splitter 3. Thus the moving state of the mobile body can be detected with high accuracy.
