Title: Optical device for measuring amount of displacement
IPC: G01P3/80
Filed: 1992-03-12
Abstract: PURPOSE:To obtain the optical device for measuring the amount of displacement which can measure the amount of relative displacement or a speed of an object to be measured in a short time and can improve measurement accuracy and dynamic range. CONSTITUTION:A laser light is shed onto an object 23 to be measured twice for obtaining two speckle pattern lights. The two pattern lights are deflected by a galvano mirror 3 and are recorded doubly to a first space light modulator 5. The double recording speckle pattern is read out and is subjected to Fourier transformation by a first Fourier transformation lens 12, thus forming Young's interference fringes. They are recorded by a second space light modulator 13. By reading out the Young's interference fringes and performing their Fourier transformation by a second Fourier transformation lens 15, a diffraction light corresponding to correlation of the doubly recorded speckle pattern is formed. By controlling a deflection angle of a galvano mirror to a value so that only a first-order diffraction light enters a PSD 16, the PSD 16 can perform a highly accurate and precise detection.

Filed: 1979-07-12
Abstract: PURPOSE: To blank a stator which does not produce any blanking strain by forming a notch to a slit edge when the width of the yoke part including the slite edge is of the specific size.  
     CONSTITUTION: Out of the yoke part 12 including a slit edge 11, the portion of A is narrower in the width of ring than 18mm and the curving due to bending moment is apt to occur; therefore a notch part 13 is formed to remove the residual strain near the slit edge.

Abstract: PURPOSE:To enable electrons-holes to be confined in a light emitting layer effectively by giving compression or tensile strain into a barrier layer. CONSTITUTION:GaP, GaAs, Si, ZnSe or the like, preferably GaP and GaAs, can be utilized as a substrate 10. A light emitting layer 13 consists of a known composition of (AlyGa1-y)mIn1-yP.
