Bleached reflection holograms produced by two plane waves in Agfa 8E56 photographic emulsion and recorded in an index-matching liquid tank at 514 nm are studied. Replay at 514 nm is both in the tank and in air, boundary reflections giving rise to multiple-output beams in the latter case. The intensities in the various output beams are measured as a function of the angle of incidence of the input beam. A simple theory based on two-wave grating diffraction and the Fresnel boundary coefficients is formulated and shown to agree with good approximation with the observed intensities of all significant output beams.
