Abstract

The application of pulsed laser in real time holography based on acousto-optic (AO) cells allows to get rid of mechanical horizontal scanning. The improvement of recently reported real time pulsed holographic display is presented. Ar-ion laser, used before as a coherent light source, is replaced with Q-switching Nd:YVO₄ laser with SHG, operated by external triggering at 46 kHz. The commercial PC dual monitor graphic card was adapted to generate six parallel analogue outputs to feed six AO cells with gray scale hologram data. The upgrade improves brightness and clearness of reconstructed images and reduces the system dimensions and power consumption. 2-D and 3-D images reconstructed from precomputed HPO holograms are presented.
