Patent JP-S62174613-A (JP)
Title: Position detector
Inventor: OKUYA NORIO
IPC: H02K11/00
Filed: 1986-06-18
Abstract: PURPOSE:To detect the position with high resolving power with a small-sized detector by using a laser light source and detecting bright and dark fringes of diffraction images generating by periodical slits. CONSTITUTION:Light emitted from a laser diode 11 is made collimated fluxs by a collimator lens 12 and projected on a moving slit plate 13. The slits 16 with width (a) arranged at the intervals d1 on the plate 13 and the Fraunhofer's diffraction images transmitted through these slits are made a combination of orderly arrangement of the same aperture and the rectangular single aperture. The diffraction images are projected on a fixed slit plate 14. The slits 17 with width (b) are arranged at the intervals d2(=d1) on the plate 14 and when the maximum interval of the diffraction images is coincident with the interval d2, the amplitude of a detected signal outputted from a photodetector 15 is made maximum. Further, since the main maximum size of each order of the diffraction images is determined by the interval d1 and the width (a), a ratio of the main maximum size <= the first order with respect to the main maximum size of the zero order can be reduced by setting (a)>=d1/2 and the stable detected signal with respect to a change of an interval between the plates 13 and 14 is obtained and the small-sized detector with high resolving power is easily produced.
