Paper Abstract

We generated a fully complex hologram by utilizing a combination of amplitude and phase spatial light modulators. A digital micromirror device (DMD) was used to produce the amplitude profile, and a liquid crystal spatial light modulator (SLM) produced the phase profile. A band-limited 4-f imaging system imaged the DMD onto the SLM to create a fully complex modulated wavefront, which reconstructed a holographic image at the desired location. We utilized backwards diffraction calculations, error-diffusion, and amplitude beam-shaping to design a hologram with small reconstruction error.
