摘要： A lens display device is disclosed. The device includes an optical thin film layer, a polarized switch unit, and a display unit emitting light. The optical thin film layer includes a single-refringent film layer, and first and second liquid crystal lens arrays on the single-refringent film layer. The arrays are positioned such that the lens elements of the first array are misaligned from the lens elements of the second array by half of the lens period. The polarized switch unit, when operative, polarizes the light emitting from the display unit into ordinary light entering the first liquid crystal lens array and into unordinary light entering the second liquid crystal lens array. In addition, when inoperative, the polarized switch unit polarizes the light emitting from the display unit into unordinary light entering the first liquid crystal lens array and into ordinary light entering the second liquid crystal lens array.

摘要： Methods, systems and apparatus for manipulating electromagnetic radiation such as laser beams. A method and apparatus for correcting magnification chromatic aberration utilises one or more dispersive lenses such that long wavelength components are magnified less than short wavelength components. A telecentric relay is preferred to achieve this aim. Further, the use of polarisers to block the undesired zeroth order components of diffraction emanating from acousto-optic deflectors (AODs) is disclosed. Furthermore, specific designs of AOD including narrow transducer AODs which produce a diverging acoustic wave and AODs having two transducers and a selection switch are disclosed. Further, the invention provides methods, systems and apparatus for allowing the wavelength of radiation to be changed, for providing a user selectable degree of compensation, for providing a scanning and/or a pointing system and for providing a compact system that does not require telecentric relays between adjacent acousto-optic deflectors.

摘要： The present invention relates to a device for doubling the frequency of laser radiation. It is an object of the invention to indicate a device for doubling the frequency of the radiation of a diode laser, which radiation is not rotationally symmetrical, with different radiation quality parameters in the vertical and lateral directions, the device having an optimum conversion efficiency or a higher conversion efficiency than the devices of the prior art. The inventive device has a laser, the irradiation of which, emitted perpendicularly to the direction of the light emitted, has a vertical divergence in a vertical direction (y) and an associated vertical radiation quality parameter (I) and a lateral divergence in the lateral direction (x) perpendicular thereto and an associated lateral radiation quality parameter (II), a nonlinear medium (1) with a quadratic nonlinear susceptibility and a focusing optical system, which focuses the laser beam in the nonlinear medium, wherein the focusing optical system is constructed in such a manner, that the focusing convergence corresponds to the radiation of the laser, focused into the medium (1), is scaled down in the vertical direction (y) of a focusing convergence, optimum for a strictly coherent radiation, by a factor, which results from the radiation quality parameter (I) along the vertical direction (y), in that this parameter is diminished by 1, then multiplied with a vertical add-on factor between 0.2 and 5 and, after that, increased by 1, and that the focusing convergence corresponds to the radiation of the laser, focused into the median (1) in a lateral direction (x) of a focusing convergence, optimum for a strictly coherent radiation, is diminished by a factor, which arises along the lateral direction (x) from the radiation quality parameter (II), in that this parameter is diminished by 1, then multiplied with a lateral add-on between 0.2 and 0.5 and, after that, increased by 1, the length of the nonlinear medium remain

摘要： Systems and methods are disclosed herein to provide zoom and/or autofocus lenses. For example, in accordance with an embodiment of the present invention, a lens is provided with at least one tunable lens. The focal length and/or focus of the lens may be varied without mechanically moving or changing the separation between one or more lens components. This is achieved by varying the refractive index of one or more lenses by means of applying a driving voltage to a nematic liquid crystal or by rotating a birefringent crystal.
Further provided is a lens manufacturing method comprising the step of preparing a lens mould by etching a patterning layer.

摘要： A focusing system for focusing an electromagnetic beam for three-dimensional random access applications comprises a first pair of acousto-optic deflectors for focusing an electromagnetic beam in an X-Z plane, and a second pair of acousto-optic deflectors for focusing an electromagnetic beam in a Y-Z plane substantially perpendicular to the X-Z plane. The second pair of acousto-optic deflectors is arranged between the acousto-optic deflectors of the first pair of acousto-optic deflectors such that the first and fourth acousto-optic deflectors of the system belong to the first pair of acousto-optic deflectors and the second and third acousto-optic deflectors of the system belong to the second pair of acousto-optic deflectors.
