摘要

Digital holography has high potentials for future 3D imaging and display technology. We present a method for a dynamic full-color digital holographic 3D display on single digital micro-mirror device (DMD) with full-color, high-speed and high-fi-delity characteristics. We combine the square regions of adjacent micro-mirrors into super-pixels that can modulate amp-litude and phase independently. Gray images are achieved by amplitude modulation and precise positioning of each col-or is achieved by phase modulation. The proposed method realizes a full-color imaging based on the three primary col-ors and achieves measured structural similarity of more than 88% and color similarity of more than 98%, while retaining the high switch speed of 9 kHz, thus achieving dynamic full-color 3D display on charge-coupled device (CCD).
