    摘要: Disclosed is an atomic force microscope. A Fabry-Perot interferometer where the intensity of light reflected at a cantilever through an optical fiber varies sensitively to a displacement of the cantilever is constructed to accurately measure a distance between the optical fiber and the cantilever. A Fabry-Perot resonator is formed by the optical fiber having an end of a concave mirror shape and a reflective surface of the cantilever. A displacement of a cantilever tip is measured by detecting a signal reflected at the resonator and a feedback signal corresponding to a variation in the displacement of the cantilever tip is generated. The displacement of the cantilever tip is kept constant by actuating a piezoelectric element in a Z-axis direction.

    摘要: A near-field optical head which reproduces, with high S/N, information recorded with extreme density and is compact in structure. On an electrode (2) is formed a recording medium (3) that emits a light by applying an electric field. Brought into proximity to a recording medium (3) is a near-field optical head (101) having a slider (31) formed with an inverted cone formed hole such that an apex thereof is rendered as a microscopic aperture (6). A microscopic electrode (5) is formed on a side surface (32) of the inverted cone formed hole. An electric field (9) is applied only to a microscopic region to cause light emission. It is possible at the aperture (6) to detect a light emitted only by the microscopic region.

    摘要: A sample analyzing apparatus includes a micro-aperture probe, which is provided with a light passage aperture having a diameter shorter than wavelengths of light, the light passage aperture being formed at a radiating end of the micro-aperture probe, and a light source, which produces light for sample analysis. An incidence optical system causes the light for sample analysis to enter into the micro-aperture probe from an entry end of the micro-aperture probe. A sample supporting member supports a sample at a position that is exposed to near field light radiated out of the radiating end of the micro-aperture probe. An image sensor receives light scattered by the sample and detects an intensity distribution pattern of the scattered light. A display device displays the detected intensity distribution pattern.

    摘要: A confocal optical system is disclosed that utilizes fiber optic components in its construction. The system includes a light source, two detection units, an aperture and an optical element all optically coupled to a fiber optic coupler via optical fibers. In addition, a novel automatic focusing device is disclosed which utilizes chromatic aberration to maintain a target object in optimal focus. The device includes two light sources having different wavelengths of light, an optical element, an aperture, two detection units and a beam splitter. One light source is used to achieve initial focus and to illuminate the target object. The second light source is used to maintain the target object in optical focus. Light reflected off the target object is measured by one of the detection units. The magnitude of the light of the second wavelength measured by the detection unit is utilized to maintain focus. A second detection units is utilized to measure the intensities of the two light sources to yield normalized results. Further, a method of diagnosing an optical system is also disclosed. The method includes comparing a current set of readings of light against a set of reference readings taken at an earlier point in time. If the difference exceeds a predetermined threshold, a problem is indicated.
