In a previous paper, several theoretical expressions were derived for calculating the ratio of the light flux in a holographic image of a uniform but extended source to that of a direct image of the source itself, account being taken of the sensitometric characteristics of the photographic material. The present paper is an experimental extension of this work. In particular, comparisons are made between theoretical curves and experimental data for variations of (1) the average density of the hologram, (2) the ratio of object-beam to reference-beam irradiances, and (3) the angular extent of the object. The performance of certain photographic developers is also discussed.
