Democratising Hyperspectral Imaging Technology
Hyperspectral imaging refers to the ability to capture the full optical spectrum at each point in an image. This technology has the potential to revolutionise industries ranging from agriculture and medicine to defense and consumer electronics. But cost is standing in the way. What if we could make this innovative technology accessible to all, and unleash its full potential on the world?
The researchers at the Palo Alto Research Center (PARC), a Xerox Company, are doing just that — engineering hyperspectral imaging technology to be lightweight, programmable and inexpensive enough for widespread use.
Based on an elegant reversal of the operating principle of a liquid-crystal display, the PARC technology relies on a liquid-crystal layer about as thick as a human hair to encode hyperspectral information. It can therefore be integrated anywhere image sensors are currently used, including on smartphones.
Soon, the whole world will have the ability to see things that up until now have gone completely unnoticed.
