Researchers from the University of Cambridge have designed a new type of pixel element and demonstrated its unique switching capability, which could make three-dimensional holographic displays possible.
Holograms made of tiny particles of silver could double the amount of information that can be stored in digital optical devices, such as sensors, displays and medical imaging devices.
A sensor which can be used to screen for diabetes in resource-poor settings has been developed by researchers and tested in diabetic patients, and will soon be field tested in sub-Saharan Africa.
A ‘trouble maker’ from a bygone method of glass production could find a new use as an optical diffuser in medical laser treatments, communications systems and household lighting.
‘Smart’ holograms, which are currently being tested to monitor diabetes, and could be used to monitor a wide range of medical and environmental conditions in future, have been developed by researchers.
A breakthrough in the use of carbon nanotubes as optical projectors has enabled scientists to generate holograms using the smallest ever pixels.
