This article reports a demonstration of off-axis compressed holography in low light level imag-
ing conditions. An acquisition protocol relying on a single exposure of a randomly undersampled
diffraction map of the optical field, recorded in high heterodyne gain regime, is proposed. The image
acquisition scheme is based on compressed sensing, a theory establishing that near-exact recovery
