    Abstract: The invention relates to apodization in a holographic direct view display. Known apodization functions are utilized/modified for an apodization mask such that the functions reduce the intensities of selected higher magnitudes of diffractions. The holographic direct view display comprises a controllable light modulator having modulator cells and modulating impinging coherent light into a phase and/or amplitude, and an array of apodization masks. The apodization masks have the same apodization function for a predetermined group of modulator cells, by means of which function a complex amplitude transparency can be set for the modulator cells. This transparency corresponds to an individually predefined course of intensity in a far field of the light modulator, wherein the predefined course of intensity includes a reducing of the light intensity of higher magnitudes of diffractions, and/or of the interfering light emitted by the light modulator.

    Abstract: A directionally controlled illumination unit is disclosed that deflects light from activated illumination elements into visibility regions by a transmissive image reproduction means. The visibility regions are tracked by the eyes of different viewers to other positions in front of the display via a tracking unit and image control. To avoid a strong correlation of one pixel of the image reproduction means to a deflection element (electro-wetting cell) of a deflection means, the directionally controlled illumination unit comprises a two-dimensional illumination means in front of the image reproduction means arranged in a serial manner in the optical path and a deflection means containing at least one field having an arrangement of electro-wetting cells that can be discretely addressed in groups and adjusted with regard to their refractive behavior by the tracking unit and image control.

    Abstract: In a pixilated spatial light modulator having a mesh-based modulator element per pixel, a real location-dependent amplitude and a location-dependent phase can be adjusted independently of each other for modulating a coherent wavefront using complex values. A complex-valued spatial light modulator includes a regularly constructed pixel array, wherein each pixel comprises a controllable reflective line mesh. The modulation of the amplitude and phase take place independently of each other in each modulator element, by relative motions of the self-supporting line mesh relative to a base plate. The line meshes are suspended and supported such that both the distance between the base plate and the line mesh (normal adjustment for amplitude modulation) and the lateral displacement of the line mesh in the mesh plane itself (phase modulation) are modified by a system controller. The reflected light is thus modulated independently of each other.

    Abstract: In the case of a method for absolute calibration of an interferometer with the aid of a spherical output wave, comprising an optical element which retroflects the incident spherical wave itself or via a mirror, at least four measuring procedures are undertaken to determine a wave aberration W. The optical element is measured in the at least four measuring positions intrafocally and extrafocally in at least two different rotational angle positions. It is also possible, in addition, to undertake a measurement via a mirror in the cat's eye position (focus 3).
