摘要： An optical ranging sensor includes a light emitting unit for projecting a light beam on an object to be measured, a light receiving unit on which a light spot of reflected light of the light beam from the object is formed, and a processing circuit unit for processing output signals from the light receiving unit and detecting a distance to the object. The light receiving unit includes an effective light receiving part having light receiving cells arranged in matrix form in a first direction in which a position of the light spot moves as the object moves along a direction of an optical axis of the light emitting unit, and in a second direction orthogonal to the first direction. A size of the effective light receiving part in the second direction is not smaller than a radius of the light spot but not larger than a diameter thereof.

摘要： A lens frame, made from metal, retaining a light-emitting lens and a light-receiving lens is retained between a second mold and a third mold both of which are made from light-shielding resins. Anchors are formed by filling light-shielding resin for forming the third mold into fixing slots formed in an upper surface of the second mold and through holes formed in the lens frame. Since the lens frame is made from metal, thermal expansion of the lens frame is hardly caused by ambient temperature changes and self-heating. This causes little difference in the amount of change in difference between the lenses. Further, the lens frame is fixed with anchors between the second mold and the third mold. This suppresses the occurrence of sliding caused by difference in thermal expansion coefficient between the lens frame and the second and third molds.

摘要： A lens frame, made from metal, retaining a light-emitting lens and a light-receiving lens is retained between a second mold and a third mold both of which are made from light-shielding resins. The lens frame has an asperity structure on its front and back surfaces. This greatly enhances adhesiveness between the light-emitting lens and the lens frame and adhesiveness between the light-receiving lens and the lens frame, thus preventing sliding of the light-emitting lens and the light-receiving lens over the lens frame.

摘要： In an optical movement information detector, light emitted from a laser diode (1) is split into a first beam (10), a second beam (11) and a third beam (12) by beam splitters (2a, 2b). The first, second and third beams are converged by a condenser lens (4) upon a surface of an object to be measured (5) to form a beam spot (13) thereon. Diffused light from the beam spot (13) is received by a photodiode (6) and an output signal of the photodiode (6) is processed by a signal processing circuit (20) including an analog-digital converter (8) and a Fourier transforming unit (9). A detecting section (21) obtains, for example, a moving velocity and a moving direction of the object based on spectrum peak frequencies obtained by the Fourier transform.

摘要： An object of the present invention is to increase efficiency in review work by appropriately narrowing down review work that verifies shapes of visual defects relating to an enormous amount of defects detected by a visual inspecting apparatus with high sensitivity. In order to appropriately extract defect information from an inspecting apparatus, a filter function and a sampling function are prepared by unitizing the functions. As a result, defects as review targets are narrowed down and extracted automatically using the filter function and the sampling function in combination. In addition, sequencing the filter conditions and the sampling conditions and registering the sequence enables automatic filtering and sampling on the basis of information on a wafer as a review target, and thereby only defect information on the review target is extracted.
