摘要： The invention relates to a device for homogenizing radiation, preferably light, with the help of chirped microlens arrays (cMLA) which, unlike standard regular microlens arrays (rMLA), are an arrangement of non-identical lenses in an array. Non-identical means that the lens parameters in the array, e.g. the radius of curvature, free diameter, vertex position, and other parameters, can vary from one lens or cell to another. The parameters of each lens or cell can be (analytically, numerically) determined by means of functions which are preferably dependent on the position of the cell or lens within the array.

摘要： The invention relates to an optical array for symmetrization of the beam of multiple sequentially fixed adjacent laser diodes, their respective output radiation being asymmetrical in relation to a first and a second direction that are perpendicular to each other. A cylindrical lens (3) with sufficient isoplanacy is mounted on the tilted optical axis (z axis), which is perpendicular to the plane predetermined by the two directions (x, y). Said lens collimates and displaces the output beam bundle of the individual laser diodes in the first direction (x). The cylindrical lens (3) is mounted downstream a directional element (4) that deflects the beam bundle of the individual laser diodes (2) in the second direction (y) with different deflecting angles respectively in such a way that the centers of gravity of the individual beam bundles converge at a predetermined spacing. A redirection element (5) is mounted in the spacing behind the directional element (4) which compensates the different deflection angles of the beam bundle to the optical axis (z axis).

摘要： The invention relates to a projection display equipped with an image generator (30), which is designed to generate individual pictures in a distribution of sub-areas (33-1 to 33-7) of an image generation plane of the image generator (30). The projection display also comprises a multi-channel optical system (40), which is configured to image one associated sub-area (33-1 to 33-7) of the image generator (30) per channel (44-1 to 44-7) in such a way that the images of the individual pictures on a projection surface are joined to form a whole picture (5). At least some channels of the multi-channel optical system (40) are arranged along at least one curve, which is similar to at least one elongated picture feature of the whole picture (5), so that a two-dimensional anisotropic blurring behavior of each pixel is achieved. In this way, a large range of depth of field can be combined with relatively high projection brightness without having to accept losses regarding the focused display of picture features that should be projected with sufficient sharpness.

摘要： The invention relates to an optical arrangement for symmetrizing the radiation of a plurality of laser diodes that are arranged adjacently to each other and on top of each other, in a fixed manner relative to each other. The output radiation of each laser diode is unsymmetrical in relation to a first direction (the y axis) and a second direction (the x axis) which are perpendicular in relation to each other. The inventive optical arrangement is particularly for use for symmetrizing the radiation of laser diode bars that are stacked on top of each other, forming a laser diode stack. A plurality of microcylindrical lens units (2a, 2b, 2c) with sufficient isoplanacy are arranged in such a way that they are tilted about the optical axis (the z axis) of the designated linear array of laser diodes, collimate the output beam bundles of the individual laser diodes of the designated linear array of laser diodes in direction y, deviating said output beam bundles to different degrees and separating them as they do so. The bundles (8) output from the laser diodes that are arranged on top of each other in direction y coincide at a set distance. A directional element (3) is mounted downstream of the microcylindrical lens unit (2a, 2b, 2c). This directional element diverts the beam bundle (8) of the individual laser diodes that are arranged adjacently to each other in direction x with different angles of deflection respectively, so that the central points of the individual beam bundles (8) coincide at a set distance. A redirecting element (5) is located at a distance behind the directional element (3) and compensates the different angles of deflection of the beam bundles (8) introduced by the directional element (3) in the plane xz.
