Off-axis digital holography typically uses a beamsplitter 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 anddemonstrates a total internal reflection hologramthat replaces the beam splitter and enables hologram recording over a large aperture with a thin camera.
