The video image projection machine which includes the holograph device and the said holograph device for the light beam formation which has specified spectral distribution

摘要

(57) Abstract The device of this invention a) is the transmitted field and the reflexive domain alternately, the plane surface mirror (7) which is formed depending upon the contiguity field (5_i and 6_i) which has the parallel boundary line in the straight line, b) 1 where each one has specified spectral distribution these diffraction beams are sent out at least, equality the 1(4) and 2nd (4 '') reflected hologram, through c) mirror (7), the illuminant in order to irradiate hologram (4,4 '') vertically to include (1), as for hologram (4,4 '') vis-a-vis the surface of the mirror (7) symmetricallyIt is laid out, the transmitted field of the mirror (6_i) and the reflexive domain (5_i) through each one, it is irradiated, the respective beam which was diffracted in addition by 1st and 2nd hologram is reflected and transmits the mirror (7) the respective reflected stripe (5_i) and the transmitted stripe (6_i), the respective reflected stripe (5_i) the diffraction beam and the transmitted stripe which are reflected (6_i) the diffraction beam which was transmitted is synthesized and becomes the continual light beam which has specified spectral distribution.
