Ferroelectric liquid-crystal-over-silicon (LCOS) microdisplays have been used to project simple 3D images.
Conducting MWCNTs can be used to build 3D electrode structures in optically anisotropic media such as liquid crystals, making novel new micro-optical components possible, according to Tim Wilkinson, University of Cambridge (Cambridge, United Kingdom). The discovery opens up reconfigurable holography to a new realm of applications which use partially coherent light sources such as LEDs. Wilkinson hopes to expand on recent success to build a viable display system for true 3D holographic images. A complete report on the use holographic display using carbon nanotubes can be found in the SPIE newsroom.
