Abstract
We present a method to perform digital holography by using a single pixel detector. It is based on combining computational ghost imaging and phase-shifting interferometry. The object is illuminated with random patterns generated with the aid of a spatial light modulator. A single pixel detector measures the interference between the light transmitted by the object and a reference beam for each pattern. The phase and amplitude distribution of the object are then measured through correlations between phase-shifted random patterns and the associated interference values. Experimental results for two-dimensional amplitude and pure phase objects are presented and discussed.
