摘要

The invention concerns colour image formation systems for displaying real or virtual, two-dimensional or three-dimensional, colour or monochrome images, and the use thereof, in particular for television and video or printing applications. The basic concept of one variant printing applications. The basic concept of one variant (a) is the use of a "unit for three-dimensional beam combination" (14) for combining three light components of different wavelengths in the visible spectrum and the diffraction of the light (LVM) thus combined in such a way as to create, by intensity or amplitude modulation and colour modulation of the light components carried out synchronously with the diffraction of the combined light (LVM), a virtual image in space or a real image on a projection screen (5) which can be perceived by the eye (12) of the observer. The "unit for three-dimensional beam combination" (14) comprises waveguides (2, 9) capable, with more or less equal effectiveness, of broad-band or spectrally selective transmission and three-dimensional combination of light. All electronic and optical assemblies for the colour image formation can be integrated on a substrate (11) in either monolithic or hybrid form. The colour picture formation system can be realised in the form of a module enclosed in a housing.
