摘要： An optical recording/reproducing apparatus has a light source that radiates a laser beam, an optical detector that detects reflected light from the optical disc, a collimator lens that converts the radiated light of the light source into a fine divergent pencil of rays, and an objective lens that focuses these rays on the optical disc. The collimator lens has a surface that is curved to form a wavefront shape that increasingly corrects a coma aberration of the radiated light in correspondence to a radial distance between the center of the collimator lens and a position at which the radiated light intersects the collimator lens.

摘要： The invention relates to a beam shaping device for shaping the cross-section of a light beam, comprising at least one beam shaping unit with beam splitting means, beam deflecting means, and beam combination means. The beam splitting means are capable of diving up a light beam that is incident on the beam shaping unit into two partial beams. The beam deflecting means are capable of deflecting at least one of the partial beams onto the beam combination means and said beam combination means are capable of combining the two partial beams in such a manner that the cross-section of the light beam exiting the beam shaping unit is reduced in size in a first direction compared to the cross-section of the light beam that is incident on the beam shaping unit and is increased in size in a second direction perpendicular thereto. the invention is further characterized in that the beam combination means can also be used as beam splitting means, whereby only one of the partial beams is deflected by the beam deflecting means, while the other partial beam is directly incident on the beam combination means.

摘要： A refractive optical element provides beam separation control for two or four light beams by refracting each beam from an incident surface through the optical element to be refracted from a parallel exit surface out of the optical element. The beams have closer beam to beam spacing after the refraction from the optical element than before. The incident and exit surfaces are angled relative to and symmetric around an optical axis.

摘要： An image projection system implemented with a projector engine using a reflective light modulator, preferably a Digital Micromirror Device (DMD), operates lying flat with very low profile on a support table. The invention overcomes the disadvantage of previous DMD projectors that require either tilting all or part of the projection system 45 degrees relative to a support table top or packaging the projection system in a thick box that allows light to impinge on the DMD from above or below its light reflecting surface. This is accomplished with a prism assembly that sets up the correct illumination angles for the DMD and directs imaging (output) light along approximately the same vector as that of illumination (input) light incident to the prism assembly. The illumination light and imaging light do not propagate in a common plane within the prism assembly, but the vectors of the illumination light entering and the imaging light exiting the prism assembly are approximately the same. An alternative preferred embodiment of the prism assembly includes a light escape window through which illumination light reflected by the DMD in its off-state escapes from the prism assembly in a direction away from the projection lens. An implementation using a third prism optically fixed to an output prism or forming an integral part of an enlarged output prism is especially advantageous because it can provide a three-point mounting of the prism assembly to the floor of the interior of the projection system housing.

摘要： An optical collimator is provided for ready fitting to an optical device with precise optical alignment, to obviate the need for adjusting the collimator during assembly to the optical device to compensate for a translational offset and an angular deviation. In an embodiment, the collimator has a sleeve with an outer cylindrical surface that is concentric with the output optical path, which has a translational offset and an angular deviation with respect to the collimator axis. A method is provided for making such a collimator for ready fitting to an optical device with precise optical alignment. In an embodiment, a portion of an outer sleeve of the collimator is removed according to the offset and the deviation to form an outer cylindrical surface that is centered about an axis which coincides with the optical path emanating from the collimator, to allow the collimator to be readily fitted to an optical device.

摘要： The invention relates to a geometrical beam splitter, e.g. in a sensor, for transversally dividing a radiation beam (4) into at least one reflected beam portion (5R) and at least one passing beam portion (5T). The beam splitter (1) is composed of a piece (11) of rigid material having a non-transparent reflective surface (3) at an angle (&agr;) deviating from the right angle in respect to the incident direction (RI) of said radiation beam. The beam splitter has a width (W) and a height (H) extending over a total effective cross-sectional area (A*) of the radiation beam (4) and e.g. two holes (2a, 2b) extending through said piece of rigid material. The holes allow passing of at least two beam portions (5T), and simultaneously the non-transparent reflective surface divert at least one reflected beam portion (5R) so that said beam portions have substantially similar wavelength distributions.

摘要： In the developed state of the combiner 13, the first arm 19 extends along a vertical line passing the center of gravity G of the combiner 13, and the second arm 21 and the third arm 23 are aligned on and extended along a line which couples the rear end of the base member 17 and the other end 19b of the first arm 19 and tilts from the vertical direction toward the horizontal direction so that the combiner 13 is arranged in front of the eye point I at a tilting angle of reflecting the image light of the displayed image emitted from the display device of the projector unit 9 toward the eye point I of the driver 3. In such a configuration, the virtual image of the displayed image on the combiner which is to be visually recognized from the eye point can be visually recognized stable with no shaking in a vehicle which is susceptible to the vibration from the road face.

摘要： The invention provides a dichroic prism capable of reducing displacements of projection pixels of colors caused by chromatic aberration of magnification. A dichroic prism is formed in the shape of a quadrangular prism as a whole by joining four rectangular prisms together. A red reflecting dichroic plane and a blue reflecting dichroic plane intersect to form substantially an X shape along junction surfaces of the prisms. The red reflecting dichroic plane is convex-shaped by partly changing the thickness of an adhesive layer for connecting the rectangular prisms together. Accordingly, since a red beam can be guided to a projection optical system while being enlarged, it is possible to reduce a projection image of the red beam to be projected onto a projection plane via the projection optical system. This makes it possible to reduce relative displacements of projection pixels of color beams caused by chromatic aberration of magnification.
摘要翻译：本发明提供一种能够减少由倍率色差引起的颜色的投影像素位移的二向色棱镜。通过将四个矩形棱镜连接在一起，二向色棱镜整体形成为四边形棱镜的形状。红色反射二向色平面和蓝色反射二向色平面相交，以沿着棱镜的连接表面形成基本上X的形状。红色反射二向色平面通过部分地改变用于将矩形棱镜连接在一起的粘合剂层的厚度而呈凸形。因此，由于红色光束可以在被放大的同时被引导到投影光学系统，所以可以通过投影光学系统减少要投影到投影平面上的红色光束的投影图像。这使得可以减小由倍率色像差引起的彩色光束的投影像素的相对位移。
