METHOD AND FACILITY FOR LIGHT-BEAM PROJECTION OF IMAGES ON A SCREEN

In a process for the projection of images on a screen (20) by means of a light bundle, an individual projector (40) is provided for projecting the images, wherein the light bundle used for projection is emitted from a light source (12, 12') in the projector (40) whose light has at least one spe...

Zusammenfassung:	In a process for the projection of images on a screen (20) by means of a light bundle, an individual projector (40) is provided for projecting the images, wherein the light bundle used for projection is emitted from a light source (12, 12') in the projector (40) whose light has at least one spectral peak in the visible wavelength range with a half-width of less than 100 nm, especially less than 30 nm, and observers of the image are given eyeglasses (24, 24') which have a wavelength-dependent transmission function such that light in the wavelength range of at least one spectral peak or, if more than one spectral peak, in the wavelength range of at least one of these spectral peaks passes through each eyeglass (24, 24'), and the light intensity for light with wavelengths beyond this spectral peak or spectral peaks is reduced.
