Filter arrangement for a wavelength division multiplex stereo system and stereo goggles, stereo projector or stereo display of a wavelength division multiplex stereo system

摘要

The invention relates to a filter arrangement 30 for a wavelength division multiplex stereo system 10. This is provided with at least one first layer-shaped filter 31, which has at least one narrow-band transmission or block area and represents an interference filter 31. Furthermore, according to the invention, at least one second layered filter 32 is provided, which is connected to the surface of the first layered filter 31 and which represents a dye filter 32. The second layered filter 32 has at least one transmission or block or absorption area, which corresponds in position to that of the at least one narrow-band transmission or block area of the first layered filter 31. All transmission or block or absorption areas preferably correspond. Furthermore, the invention relates to stereo glasses 20, a stereo projector 12 or a stereo display, each of which is provided with at least two filter arrangements 30 according to the invention, the narrow-band transmission or block or absorption regions of these filter arrangements 30 having no mutual overlap. This invention enables an efficient and inexpensive implementation of a wavelength multiplex stereo system 10.
