“…This can be further simplified by substituting (5) to yield (6) (7) (8) (9) absorption . Since -iis a direct indication ofthe measured intensity ratios, we can use this relationship to predict the optimum beam ratio for maximum average fringe contrast, thus maximum hologram efficiency.…”

The recording of holograms in which the reference beam enters through the supporting substrate involves attenuation factors which differ strongly between signal and reference. This paper addresses the issue of fringe contrast under these extreme conditions and provides quantitative data that are indicative of at least a partial solution to the problem. We define a spatial average for the fringe contrast and offer results which follow our theoretical model for Du Pont OnmiDexTM photopolymers. The direct edge referenced technique for recording is re-visited with observation of a new phenomenon which we call self-induced index matching. An alternative fringe recording geometry is proposed and compared with direct recording.

“…Another benefit of TIR holograms is that compact optical systems can be designed by folding the optical path, as in the edge-illumination geometry proposed by Upatnieks [3][4][5]. This geometry has been analyzed by Phillips and co-workers [6,7].…”

Off-axis digital holography typically uses a beam splitter to combine reference and object waves at an angle matched to the sampling period of the sensor array. The beam splitter determines the thickness of the recording system. This paper describes and demonstrates a total internal reflection hologram that replaces the beam splitter and enables hologram recording over a large aperture with a thin camera.
