Since the invention of the stereoscope in 1838, new technology has improved the 3 necessary conditions to simulate depth from 2 flat images: 1) a means to capture left and right perspective views; 2) a menas to combine, or multiplex those views; 3) a means to deliver each view to the correct eye, or de-multiplex. To date, VRex inventions and improve-ments have led to a comprehensive sereoscopic line of 3D LCD displays, stereoscopic cameras and electronic multiplexers, 3D polarized hardocpy, 3D printing inks, 3D shutter glasses, 3D computers, and 3D systems pacing the invevitable transition from 2D to 3D imaging. We will outline four basic technologies developed at VRex to implement these stereorscopic system: first, #mu# Pol micropolarizers for spatial multiplexing; second, improvements in LCD shutters and synchronization techniques for field-sequential or temporal nultiplexing; third, spectral multiplexing for flicker-free field-sequential displays at standard video rates; fourth, Cholesteric Liquid Crystal (CLC) inks for stereoscopic printers, artwork, and other 3D hardcopy.
