摘要： A focus error detection device to be used in an optical system for recording and/or playing back information, including a light detector made up of four light receiving elements arranged symmetrically with respect to the center of the light detector, a multiplication means for generating a pair of multiplication signal by multiplying output signals of two light receiving elements which are arranged symmetrically with respect to the center of the light detector. The multiplication signals are applied to a subtraction means where the focus error signal is generated by the subtraction between the multiplication signals. Thereby the off-set of the focus error signal which has been caused by the deviation of the position of the center of the light beam from the center of the light detector is by far reduced.

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： According to the present invention, there is provided a method of designing a collimator array device which enables reduction of the insertion loss because of the variation of the optical length. When the beam waist is positioned at the intermediate position between the emitting side planar microlens and the receiving side planar microlens (d1=L/2), the distance d0 between the emitting side fiber array and the emitting side planar microlens can be used as the distance between the receiving side fiber array and the receiving side planar microlens, and thereby the design of the collimator array device can be simplified. The distance d0 for satisfying d1=L/2 is calculated and two values d0-2 and d0-4 are obtained. By selecting the smaller value d0-2, it is possible to reduce the insertion loss because of the shift at the time of coupling.

摘要： The present invention provides a method for manufacturing an erect image, unity magnification, resin lens array by injection molding. Two injection-molded lens plates are stacked such that convexly warped sides thereof face each other or such that a convexly warped side of the lens plate whose warp is greater than that of the other lens plate faces a concavely warped side of the other lens plate, while directions of resin injection thereof are aligned so as to optically avoid the influence of molding shrinkage. Engagement spigots and engagement sockets are employed in order to align the two lens plates. The two stacked lens plates are secured by clipping of peripheral portions thereof.

摘要： A liquid-crystal display device has a planar microlens array and a liquid-crystal display panel coupled with the planar microlens array. The planar microlens array comprises an array of convex microlenses provided on a surface of a base glass plate. The array of convex microlenses is made of an ultraviolet-curable synthetic resin having a relatively high refractive index. A cover glass plate is joined to the liquid-crystal display panel and has a peripheral edge bonded to a peripheral edge of the array of convex microlenses. The cover glass plate is spaced from the array of convex microlenses by a hermetically sealed space which is filled with an inactive gas such as dry nitrogen gas, argon gas, or the like. The surfaces of the convex microlenses may be coated with an anti-oxidation film.
