IPC: G01B11/00
Filed: 1987-03-02
Abstract: PURPOSE:To enable the highly-precise measurement of a three-dimensional position, by a method wherein first and second cameras picking up an object from different directions are oscillated at a prescribed frequency and signals from the cameras are subjected to waveform processing.

Abstract: PROBLEM TO BE SOLVED: To adjust inclination of an object lens without inclining an optical pickup by rotating a ball spline which rotates a freely rotatable bit which is to be engaged with an adjusting screw and also moves the bit straightly toward the tightening direction of the adjusting screw with a rotating means. SOLUTION: The tip of a bit 48 is inserted into the plus groove of the adjusting screw of the optical pickup by elevating a bit rotating unit. When directions of the plus groove of the adjusting screw and the bit 48 do not match at this time, a spring 47 pushing up a ball spline direct drive part 46 is shrinked and the bit 48 is lowered to escape from the adjusting screw and it does not apply a large force to the pickup. Moreover, it never imparts the inclination on the optical pickup by regulating the engaged depth of the bit 48 with respect to the adjusting screw with stoppers 49, 50 so that a force equal to or larger than a needed force due to the energizing force of the spring 47 is not applied to the optical pickup when the bit 48 is engaged with the adjusting screw.

Abstract: PROBLEM TO BE SOLVED: To provide an infrared detector which reduces a surface leakage current in a mesa part and whose characteristic is excellent in the infrared detector which uses an HgCdTe crystal and which is of a mesa-type structure. SOLUTION: A p-HgCdTe layer 2 is formed on an n-HgCdTe layer 1, a protective film 3 having a positive fixed electric charge is formed on the surface of a mesa-type structure in which a p-n junction is isolated by an etching operation, and a protective film 4 which does not have a fixed electric charge is formed on the protective film 1 having the positive fixed electric charge. Since the anodic oxide film 3 having the positive fixed electric charge is formed on an etched wall surface and an etched bottom face which are damaged and whose crystallinity is bad, electrons are induced near the boundary between the film and the crystal protective film due to the influence of the positive fixed electric charge, and an inversion region is formed in the region of the p-HgCdTe layer 2.  As a result, the p-n junction is moved to the inside from the damaged region, and a surface leakage current can be reduced.
