摘要： A pattern reading apparatus reads a pattern from a reflective object. The pattern reading apparatus includes a minute-area light source, an objective lens system, an imaging lens, and an imaging element. The objective lens system causes the illumination light beam from the light source to be incident on the object and converges the light beam reflected from the object. The imaging lens forms an image of the object using only a scattered component of light which has been reflected from the object. The imaging element is positioned such that the image of the pattern is imaged for reading the pattern. A shift mechanism is provided for supporting the objective lens for movement parallel to a direction approximately perpendicular to the optical axis of the objective lens.

摘要： The method of manufacturing an optical lens in accordance with the present invention includes a drawing optical lens preform preparing step of preparing a drawing optical lens preform comprising a first curved face part, formed aspheric in one side face thereof, functioning as an optically active part, and a second curved face part, formed in a side face opposite from the first curved face part, having a curvature smaller than that of the first curved face part; a drawing step of drawing the drawing optical lens preform to a desirable outer diameter; and an optical lens preparing step of preparing an optical lens 1 by slicing the drawn drawing optical lens preform. Since the second curved face part is formed, distortions can be restrained from occurring due to the drawing in this manufacturing method.

摘要： The present embodiments provide methods, apparatuses, and assemblies for use in producing a desired output beam that meets a desired intensity prescription. An apparatus can include an input surface, and an optically active output surface that receives a collimated beam, such that the output surface refractively maps an illuminance distribution of the collimated beam into a prescribed intensity pattern. The apparatus can include a collimating lens that collimates an input beam. Additionally, the output surface can be defined according to a cumulative illumination integral for the illuminance distribution and a cumulative illumination integral of the intensity pattern. Some embodiments provide methods that can determine an illumination integral for an illuminance pattern of an input, determine an intensity prescription, establish a spatio-angular correspondence of the input beam with the intensity prescription, derive surface normal vectors, and determine the output surface according to the surface normal vectors.

摘要： High spatial frequency optical noise in the form of intensity contrasting picture elements in the display of a projected light image on a bead-oriented image-enhancing filter is significantly reduced by interposing light-scattering material in the optical path between a source of the projected light image and the display in order to inhibit formation and interference of coherent light waves, and to mask the appearance of separate or discrete beaded apertures.
