Abstract
The present invention relates to a light modulating device, comprising a SLM and a pixelated optical element, in which a group of at least two adjacent pixels of the SLM in combination with a corresponding group of pixels in the pixelated optical element form a macropixel, the pixelated optical element being of a type such that its pixels comprise a fixed content, each macropixel being used to represent a numerical value which is manifested physically by the states of the pixels of the SLM and the content of the pixels of the pixelated optical element which form the macropixel.

A light modulating device, comprising a spatial light modulator and a pixelated optical element, in which a group of at least two adjacent pixels of the spatial light modulator in combination with a corresponding group of pixels in the pixelated optical element form a macropixel, wherein the pixels of the pixelated optical element comprise a fixed content, and the pixels of the spatial light modulator comprise a variable content, wherein each macropixel represents a numerical value being an amplitude value or a phase value or a complex valued number for separately controlling the amplitude and the phase of an incoming light wave, which is manifested physically by the effect of combination of the states of the pixels of the spatial light modulator and the content of the pixels of the pixelated optical element which form the macropixel.
The light modulating device of claim 35 in a holographic display according to claim 43, wherein the scatter means is designed such that a suppression of higher diffraction orders in the plane of a virtual observer window of a holographic display is achieved.
