Holographic Data Storage with a Digital Micromirror Device

A holographic data system writes bits by recording the interference between a reference beam and an object beam containing data as a diffraction grating onto a photosensitive disc. The purpose of this research is to evaluate current designs and consider improvements such as the use of a digital micromirror device (DMD) as a spatial light modulator. Other factors addressed are multiple incident angles for volume layering and improving bit contrast.
