Abstract:
The present invention relates to a light modulator device with a spatial light modulator, a structured polarizer means, a controllable polarization means and a light wave multiplexing means. The spatial light modulator comprises discretely addressable modulator cells. Two modulator cells each are combined to form a modulation element. The modulator cells modulate light waves which are capable of generating interference of a propagating light wave field with holographic information in a spatially structured way such that a specifiable spatial distribution of object light points of a three-dimensional scene is holographically reconstructed. The modulator cells of each modulation element are adjacently arranged regarding the direction of propagation of the light wave field. The light which is modulated by adjacently arranged modulator cells is given different polarization states by the structured polarizer means.
