This paper introduces a new method to realize off-axis incoherent digital holography using a spatial light modulator. The hologram is made by the interference between non-modulation beam and modulated beam from the same object. This method is beneficial by its single shot recording and simple and noise-resistant set-up. An experiment using micro-beads shows promissing result.
