DEVICE FOR PROJECTING A STEREO IMAGE OR STEREO PARTIAL IMAGE

摘要

The invention relates to a device (1) for projecting a stereo image or stereo partial image for a wavelength division multiplexing stereo system. The device (1) has one or two projection units (PE1, PE2), each having: its own housing (10); a blue laser light source (LQ1, LQ2); a photoluminescent body (PK1, PK2), which is assigned to one of the blue laser light sources (LQ1, LQ2) and is designed and arranged such that in each case one photoluminescent body (PK1, PK2) is irradiated with blue laser light (LB1, LB2) by the blue laser light source (LQ1, LQ2) such that said photoluminescent body emits broadband light (L1, L2); and a filter assembly (FA1, FA2), which is designed and arranged such that the emitted broadband light (L1, L2) is filtered into at least one narrow-band red part-spectrum (R1, R2) and one narrow-band green part-spectrum (G1, G2), wherein the part-spectra (G1, G2, R1, R2) and the blue lights (LB1, LB2) of the laser light sources (LQ1, LQ2) are selected such that the projected stereo partial images are formed mutually orthogonally to one another. Furthermore, at least one part-spectrum (G2, R2) is implemented by two narrow-band, adjacent sub-spectra (G21, G22; R21, R22) with a small spacing. The device (1) according to the invention has a compact, robust structure, which proves very efficient.
