20090021814 | HOLOGRAM APPARATUS AND METHOD THEREOF - Hologram recording and reconstruction apparatuses and method thereof are provided. The hologram recording apparatus comprises a laser source, a spatial light modulator, and a Fourier lens. The laser source provides a coherent light beam. The spatial light modulator receives m-bits data to only determine a (p×q) block comprising ON-pixels less than OFF-pixels, and receives the coherent light beam to modulate with the (p×q) block to generate the signal beam. The Fourier lens focuses the signal beam on the hologram recording medium, so that when the focused signal beam and a focused reference beam is modulated together, the hologram data is generated to be recorded on the hologram recording medium. | 01-22-2009 |
