Abstract:
1. Holographic direct-view display, comprising At least one controllable spatial light modulator with a matrix of modulator cells for diffracting light, said spatial light modulator realising an individually predefined intensity profile in the far field of the light modulator, An array of apodisation masks, where each modulator cell for modulating the phase and/or amplitude of sufficiently coherent light is assigned to an apodisation mask, At least one defined group of modulator cells which are assigned to apodisation masks with an identical apodisation function, and A complex amplitude transparency which is set for the at least one group of modulator cells and which sets the apodisation function for this group of modulator cells according to the predefined intensity profile which is to be realised, where the predefined intensity profile includes a reduction in the luminous intensity in a selected range of preferred diffraction orders.
