    摘要: A method for detecting a minute displacement of a probe includes an emission from a light source of two light beams having different polarizing directions. The light beams are subsequently diverged by a first lens so as to pass through a beam splitter towards a separating prism. The light beams having passed through the prism are separated into first and second measuring beams which are subsequently focused by a second lens on first and second, spaced reflecting surfaces. The first and second measuring beams are then reflected by the first and second reflecting surfaces, respectively, so as to enter respective photodetectors after having passed through the separating prism, the beam splitter and a polarizing beam splitter for passing therethrough the first and second measuring beams or reflecting them depending on the polarizing direction of the incoming light. The first and second photodetectors outputs respective signals indicative of the associated positions of foci which are then processed by a signal processing circuit to provide an indication of the minute displacement of the probe.

    摘要: A displacement detector device has a source of laser beam; a diffraction grating for separating the laser beam into a plurality of beam components; a filter for shielding the beam components other than the two beam components of .+-. primary order produced by the diffraction grating; a wavelength plate operable to vary the polarized state of one of the two beam components of .+-. primary order; a lens element for focusing the two beam components of .+-. primary order on a displacement plane and a reference plane, respectively; and a photosensor. The two beam components of .+-. primary order focused on the reference and displacement planes, respectively, are subsequently reflected therefrom and are then collimated by the lens element after having again entered the lens element in substantially overlapped relationship. The two beam components emerging from the lens element are again diffracted by the diffraction grating, and the photosensor detects an interfering component of the beam components of primary order.

    摘要: A three-dimensional measurement probe that is less likely to break, that is of long lifespan, and that is of low cost, capable of measuring the shape and the like of a measuring object such as an aspheric lens with higher precision is realized. A magnetic force for preventing rotation and axial displacement of a small slidably moving shaft part is generated by constructing a magnetic circuit by a magnet attached to a small air bearing part, a yoke, and a magnetic pin attached to the small slidably moving shaft part. The three-dimensional measurement probe is able to perform measurement from below and from the side since the magnetic force is non-contacting.

    摘要: Substantially collimated displacement detection light is led to a first lens and condensed by the first lens to proximities to a reflecting surface of a probe. The reflected light is displaced by an atomic force acting against a surface of a sample, where the reflected light varies in reflection angle according to the displacement. The displaced light is lead to the first lens, changed in direction by a mirror, and detected by magnifying the displacement of the probe. The detection further includes steps of moving a Z direction scan block in a direction vertical to the sample surface by a Z direction driving device, the Z direction scan block having the first lens and the probe, moving an X direction scan block in a first axial direction within a plane parallel to the sample surface by an X direction driving device, the X direction scan block having the Z direction scan block, the Z direction driving device, and the mirror, and moving a Y direction scan block by a Y direction driving device in a second axial direction perpendicular to the first axial direction within a plane parallel to the sample surface, the Y direction scan block having the X direction scan block, the X direction driving device, the detection light radiation system, and the displacement detection system.
