Method for producing volume reflection holograms with substrate-guided reconstruction beams and/or substrate-guided diffracted beams in a single-beam set-up

An apparatus for producing volume reflection holograms with substrate-guided reconstruction beams and/or substrate-guided diffracted beams in a single-beam set-up, comprising:

• at least one laser beam source, and
• a reflector arrangement,
• wherein the at least one laser beam source and the reflector arrangement are arranged with respect to each other in such a way that a transparent substrate carrying a holographic recording medium may be arranged between the at least one laser beam source and the reflector arrangement, the substrate having a first flat side facing the at least one laser beam source and a second flat side facing the reflector arrangement, wherein the holographic recording medium is arranged on the first flat side or on the second flat side,
• wherein the at least one laser beam source is configured to produce a recording beam having a first wave vector,
• wherein the beam path of the recording beam is configured such that the recording beam irradiates the holographic recording medium, passes through the holographic recording medium and is reflected by the reflector arrangement towards the holographic recording medium as a reflected beam having a second wave vector,
• wherein the beam path of the recording beam is further configured such that the reflected beam produces an interference pattern with the recording beam in the holographic recording medium, the interference pattern having the form of a grating having a grating vector, the grating vector being the difference vector of the second wave vector of the reflected beam and the first wave vector of the recording beam, and the grating vector also being the difference vector of a wave vector of a diffracted beam and a wave vector 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 of the grating is parallel to the line of intersection of the first plane and the second plane.
