    摘要: In a laser light multiplexing apparatus: a collimating optical system collimates light beams emitted from semiconductor lasers so that the slow axes of the light beams become coplanar, and optical axes of the light beams become parallel to each other; a light beam rearrangement optical system constituted by prisms respectively arranged in correspondence with the light beams rearranges the light beams in such a manner that directions of the fast axes of the light beams are changed at different locations along a direction in which the light beams propagate, and the fast axes of the light beams become coplanar; and a convergence optical system converges a bundle of the light beams rearranged by the light beam rearrangement optical system, in directions of the fast axes and the slow axes of the light beams, and makes the converged bundle of the light beams enter an optical fiber.

    摘要: A light guide plate has a hologram pattern on a light exit surface. The hologram pattern anisotropically diffuses light in the direction parallel with a light incident surface of the light guide plate. On a back surface of the light guide plate are formed mirror-polished prism structures extending parallel with the light incident surface. A downward-pointing prism sheet with a given prism apex angle is placed on the light exit surface of the light guide plate. The use of the downward-pointing prism sheet together with the light guide plate having the anisotropic diffusion hologram pattern integrally formed thereon produces a liquid crystal display device with enhanced luminance properties.

    摘要: A light-emitting unit comprises a light emitter made of a semiconductor or a light emitter which is of an electron exciting type. The light-emitting unit further comprises a prism array which is arranged in the vicinity of the front of the light emitter and converts output light rays from the light emitter other than those in a predetermined angle range into light rays in the angle range.

    摘要: The invention relates to an image reversion system (500) which enables an image reversion and beam transposition of a plurality of observation beam paths (503a, 503b, 504a and 504b) to be carried out simultaneously. The system includes at least one Porro prism system and is designed in such a way that it can be arranged in a convergent beam path. The inventive system is suitable as an image reversion system in an ancillary module for operational microscopes used in ophthalmoscopy due to the low overall height thereof.

    摘要: Prism elements having TIR surfaces placed in close proximity to the active area of a SLM device 302 to separate unwanted off-state 324 and/or flat-state 326 light from the projection ON-light bundle 322. The TIR critical angle of these prisms is selected to affect either the off-state light or additionally, any portion of flat-state light reflected from the SLM. These TIR surfaces are placed to immediately reflect the unwanted light as it comes off the SLM, thereby preventing the contamination of light along the projection path, which tends to degrade the system contrast. To further improve the optical performance of the system, these TIR prisms can be attached directly to the SLM package 300, completely eliminating the package window. Also, these TIR prism can be coupled to DMDs having asymmetric mirrors, which tilt through a larger angle for the ON-light to provide high etendue and lumen output, but through near-zero degrees for the OFF-light, thereby improving the separation of any unwanted light from the off/flat states.

    摘要: An optical wedge compensates for a vertically drifting laser beam in response to ambient temperature fluctuations. A slit sensor is formed onto a surface of the wedge to separate a single light pulse from a plurality of light pulses. A reflective filter layer is applied to a side opposite the slit sensor so an incident laser beam is attenuated thereby precluding damage to the slit sensor. The reflective filter coating further filters out unwanted light energy. The wedge is shaped so as to maintain a position of a focal point of a laser beam on the slit sensor and to prevent reflected light from damaging a laser source.
