METHOD FOR PRODUCING VOLUME REFLECTION HOLOGRAMS WITH SUBSTRATE-GUIDED RECONSTRUCTION BEAMS AND/OR SUBSTRATE-GUIDED DIFFRACTED BEAMS IN A SINGLE-BEAM SET-UP

The invention relates to a method for producing volume reflection holograms with substrate- guided reconstruction beams and/or substrate-guided diffracted beams in a single-beam set- up, comprising the steps of (i) providing at least one laser beam source (100) producing a recording beam (101, 102) having a first wave vector (201, 302b, 307), (ii) providing a holographic recording medium (107, 200) on a transparent substrate (106), the substrate (106) having a first flat side facing the at least one laser beam source (100) and an second flat side facing away from the at least one laser beam source (100), wherein the holographic recording medium (107) is arranged on the first flat side or on the second flat side, (iii) providing a reflector arrangement (103, 103') arranged on the second flat side of the substrate (106), wherein the recording beam (101, 102) irradiates the holographic recording medium (107), wherein the recording beam (101, 102) passes through the holographic recording medium (107) and the substrate (106), and is reflected by the reflector arrangement (103, 103') towards the holographic recording medium (107) and the substrate (106) as a reflected beam (104) having a second wave vector (202, 303b, 306), wherein the reflected beam (104) produces an interference pattern with the recording beam in the holographic recording medium (107), the interference pattern having the form of a grating (110, 203) having a grating vector (305), the grating vector (305) being the difference vector of the wave vector (303b, 306) of the reflected beam (104) and the wave vector (302b, 307) of the recording beam (101, 102) and the grating vector (305) also being identical to the difference vector of the wave vector (303a) of a diffracted beam and the wave vector (302a) of a reconstruction beam, and wherein a first plane spanned by the recording beam and the reflected beam is different from a second plane spanned by the reconstruction beam and the diffracted beam and wherein the grating vector (305) of the grating (110, 203) is parallel to 30 the line of intersection of the first and the second plane. The invention further relates to an apparatus for producing volume reflection holograms with substrate-guided reconstruction beams and/or substrate-guided diffracted beams in a single-beam set-up..
