Eye-glasses for viewing stereoscopic images or a perspective sub-image of a stereoscopic image, comprising at least one interference filter that has at least one photosensitive polymer film and at least two separated filter regions, said filter regions being superimposed along at least one normal line that stands vertically on a first outer surface of the interference filter, between a first point at which the normal line pierces the first outer surface and a second point at which the normal line pierces a second outer surface of the interference filter after having passed through said interference filter proceeding from the first point, and said filter regions being, along said normal line, at least substantially impermeable to a respective predetermined wavelength interval of the electromagnetic spectrum.

A viewing device for a stereo projection system, having a first and a second viewing window, each having an optically filtering filter layer system, wherein each viewing window has a filter spectrum in the visual spectral range having a plurality of pass bands that are separated from each other by blocking regions, and wherein each pass band of the filter spectrum of the first viewing window is covered by an associated blocking region of the filter spectrum of the second viewing window. Each filter layer system can be designed as an absorption filter layer system having a plurality of substances absorbing in differing spectral ranges, wherein at least one of the absorbing substances is a cyanine dye in the supramolecular configuration of a J-aggregate.

A display device for displaying stereoscopic images is provided, wherein partial stereoscopic images are generated in spectral ranges at least partially different from each other, and wherein narrow-band emitting emission elements are present for generating images, and wherein different emission elements are present for generating spectrally narrow-band optical radiation in different spectral ranges, of which at least one comprises a light-converting material excited by an excitation element for emitting optical radiation.

A stereo-projection device comprises at least one light source, at least one collimator for converting visible light generated by the light source into light with a substantially parallel beam path, and at least one interference filter which is transparent at a given angle of incidence for at least one wavelength interval having an interval width of at most 50 nm and which is designed to cross the light with the substantially parallel beam path.

We demonstrate a significant improvement of the color and transmission performance of a complementary interference filter system used for stereoscopic imaging. A 3D transmission of 30% for a UHP lamp projection system was achieved. The differences in color and luminance between left and right filter were minimized. © 2011 SID.
