摘要： A light detection device for detecting an optical path position of invisible light. The detection device includes a main body and a light guide. The light guide includes a distal end functioning as a light incident portion through which the detected light enters and a light radiation portion from which visible light is emitted. A drive mechanism reciprocates the light guide in an X-direction while vibrating the light guide in a perpendicular Y-direction. The distal end of the light guide rod moves within a light detection area in an XY plane. A visible light-emitting unit radiates visible light from the distal end when the detected light enters the distal end. The visible light-emitting unit includes a photo-detector for detecting the detected light and a light-emitting element for generating the visible light when the photo-detector detects the detected light.

摘要： A glass substrate is irradiated with a converged laser beam to thereby form a spherical or nearly spherical convex portion on a surface of the glass substrate. More preferably, there may be used a method including the steps of: sticking a glass substrate to a flat member having a predetermined spherical or aspherical concave portion formed therein; and irradiating a converged laser beam onto a surface of the glass substrate just under the concave portion while making the converged laser beam penetrate through the flat member to thereby form a spherical or aspherical convex portion in the inside of the concave portion in accordance with the shape of the concave portion.

摘要： An optical module 31 is provided in which a wavelength division element 32 such as an optical multi-layer film or diffraction grating is united between the sides of lens blocks 3 of optical module units 1 and 6 opposed to optical fiber blocks 2. Only light with a wavelength λi among light (wavelength components: λ1, λ2 . . . λn) from an optical fiber 41 is transmitted through the wavelength division element 32 and enters an optical fiber 42 of the optical module unit 6. On the other hand, the light (wavelength components: λ1, λ2 . . . λn−λi) reflected at the wavelength division element 32 is taken out of an optical fiber 43 of the optical module unit 1.

摘要： An object beam divided by a light dividing means 12 is caused to enter a photo-refractive polymer layer 6 through an optical fiber 23. On the other hand, a reference beam divided by the light dividing means 12 is irradiated on the photo-refractive polymer layer 6 through a lens 13 from the opposite side. In this manner, the object beam is superimposed on the reference beam in the photo-refractive polymer layer 6 to provide an interference fringe or pattern. Since a photo-refractive polymer has a specific characteristic whereby the refractive index changes according to the intensity of irradiation light and the change is fixed after the irradiation light is stopped, a diffraction grating 5 corresponding to the interference fringe is recorded on the photo-refractive polymer layer 6. This diffraction grating 5 exhibits a specific characteristic whereby the object beam emitted from the optical fiber 23 is emitted in the direction of the reference beam.

摘要： A reflective or transmissive image display device having a light-transmissive panel to which illuminating light for illuminating pixels is applied. The light-transmissive panel has laminated glass substrates having respective first and second planar microlens arrays. The glass substrates have their thicknesses adjusted by grinding to equalize focal lengths and other parameters of the first and second planar microlens arrays to preset values. Lenses of the first and second planar microlens arrays are formed by etching recesses in fire-finished surfaces of the glass substrates and filling the recesses with a synthetic resin having a high refractive index.

摘要： A microlens array of high converging efficiency is provided, independently of the array and lens filling rate of microlens arrays, with a method of manufacturing microlens arrays using the diffusion process. A multitude of refractive-index distribution type microlenses formed by diffusing in a planar transparent substrate a substance contributing to increasing the refractive index of the substrate are two-dimensionally and regularly arranged on the surface of the substrate. The microlenses are densely arranged on the surface of the substrate, and diffusion fronts of the microlenses form regions where the diffusion fronts are fused with those of the adjoining microlenses. The length of a region where certain two adjoining microlenses are fused together, in the direction of a straight line connecting the centers of the two microlenses is less than 20% of the array pitch of the microlenses in the above-mentioned direction.
