Real-time transmission of a 3-D image using volume scanning and spatial modulation

Theoretical and experimental investigations on real time transmission of a 3-D image using volume scanning and spatial modulation are described. By using a phase stabilized spatial modulation, a 3-D image is transmitted in real time at the rate of fifteen 3-D images per second. The signal and noise, the effect of continuous illumination, and the conditions for distortion-free imaging are shown with experimental verifications. The present system can be realized with presently available optical and electronic components.
