摘要： A method for forming many microlenses comparatively easily and effectively is provided. On one end of an optical substrate is formed a plurality of lens planes at regular intervals. Lens areas containing the lens planes are partially covered by an etching mask and etching processing is performed on areas being exposed outside the etching mask to remove the areas to a specified depth. While the lens planes formed on one surface of the optical substrate are being held by a support substrate, polishing processing is performed on another end face of the optical substrate and each microlens formed in the lens areas is separated from the support substrate.

摘要： A projection lens system which includes a telecentric lens assembly. The lens may be used to form an image from a light source, including for example a resonant microcavity phosphororcathode ray tube, onto a screen or display, such as in a television or a projection device. In accordance with one embodiment, a planar cooling gap or cavity (which may or may not contain a cooling liquid) is included between the imaging surface and the matching planar surface of the field lens. The use of a planar gap alleviates any temperature differentials across the cooling liquid and the lens surfaces, as compared with alternate designs that may have a non-planar gap between the faceplate and the field lens, or that use liquid lenses.

摘要： The claimed invention provides a self-actuating lenticular display assembly that places the lenticular image in intimate contact with the lenticular lens while maintaining the lenticular image separate from the lenticular lens to form the lenticular display. The lenticular display assembly further comprises a rigid back plate placed behind the lenticular display so that the lenticular image moves in a parallel plane between the lenticular lens and the rigid back plate, a motor that accomplishes movement of the lenticular image in relation to the lenticular lens, alignment mechanisms that allow the lenticular image to be incrementally adjusted in relation to the lenticular lens, and different means for maintaining intimacy between the lenticular image and the lenticular lens, thus eliminating undesirable nullsoft spotsnull that may occur. Alternative embodiments are also presented that relate to, among other features, a flexible, removably attached back plate, a nulldwellnull feature provided near the mid-point of image excursion, and a mechanism that permits selection of a desired image display sequence.

摘要： A flat-panel projection display comprises a transparent slab and integral area grating, a transparent rod with rectangular cross-section and integral linear grating, arranged along the edge of the slab, and a small video projector. The projector is arranged to direct a virtual image into the end of the rod, directly or via mirrors, the light travelling along the rod via total internal reflection. The linear grating diverts the light into the plane of the slab, and the area grating projects it out of the slab towards a viewer, so that the viewer sees an image at infinity.

摘要： An illumination optical system for illuminating an illumination area on an illumination surface based on a light from a light source has a wavefront dividing type optical integrator and a light source image enlarging member. The wavefront dividing type optical integrator is arranged in an optical path between the light source and the illumination surface which forms a plurality of light source image. The light source image enlarging member is arranged in an optical path between the light source and the optical integrator at or near a position optically conjugate with the illumination surface. The light source image enlarging member enlarges the light source image. The illumination area has a slot shape with a first dimension and a second dimension which is perpendicular to the first dimension and the light source image enlarging member stretches the light source image along the first direction corresponding to the first dimension.

Methods, devices and device components are presented for separating closely spaced optical channels with minimized cross talk. The invention provides optical interference filters having parallel phase control elements which efficiently transmit light of a selected optical channel or a plurality of selected channels with decreased light loss, particularly decreased insertion loss. An exemplary interference filter of the present invention provides minimized vertical and horizontal recombination error and improved optical path length matching. The invention further provides methods of fabricating optical interference filters with improved piece-to-piece reproducibility. The methods, devices and device components provided herein are particularly well-suited for combining or separating closely spaced optical signals corresponding to transmission channels of a selected frequency standard, such as the International Telecommunication Union frequency standard.

摘要： A three-port optical polarization beam combiner is disclosed. It is used for combining two optical pump beams to increase optical pumping power in a DWDM optic fiber transmission system. The combiner will combine two beams with orthogonal polarizations into one and transmit it to another port for output. By non-reciprocal effect of a half-wave plate and a Faraday rotator, the reverse noise will be blocked to improve transmission quality and protect the laser lens.
