Holographic smart pixels research highlighted by Materials Views

CDT student Calum Williams and CDT supervisor Prof. Tim Wilkinson, along with other researchers from the engineering department at the University of Cambridge have proposed a new type of pixel element and demonstrated its unique switching capability.

Holography is an optical technique that records information on both the phase and amplitude of light and can therefore be used for 3D image reconstruction. 

Researchers from the engineering department at the University of Cambridge have proposed a new type of pixel element and demonstrated its unique switching capability. The work started with the fact that a backplane surface of a typical liquid crystal on silicon display pixel element provides little optical functionality other than reflecting incident light. Therefore, a relatively large area exists in which additional functionality can be added through the patterning of nanostructures (optical antennas) to increase the channel capacity of pixels in order to fulfil bandwidth requirements of electro-holography.
