Abstract

In processes of holography using bacteriorhodopsin-based recording media, it is essential to design the signal-to-noise ratio to be as favorable as possible. This is achieved by recording the hologram using circularly polarized light and reconstructing the hologram by using linearly polarized light, specific beam components being selected as a function of polarization in the beam path of the reconstructed hologram. The process is suitable both for purely holographic applications and also for other processes which include one or more intermediate or partial steps involving holography.
