Holovideo Monitor

The goal of this research is to create a consumer-priced, holographic video monitor that runs from a standard analog video input (VGA or DVI-I) , is capable of standard video resolution (480 vertical lines), 30Hz refresh and full color operation.

The proof of concept display ran at 150 vertical lines at 5Hz or 18 vertical lines at 30Hz (display parameters like frame rate and resolution are fluid in this type of display geometry).  Within the next few weeks, work will be completed on the second prototype monitor, which will be capable of 18 times greater resolution for a full 480 vertical lines and 30Hz refresh.  The output images shown below were generated using a bulk-wave acousto-optic modulator.  However, this display can be run using other spatial light modulators as well.
