LUMINESCENT FILMS: Transparent image sensor is based on luminescent concentrator

摘要

A new way of capturing images based on a flat, flexible, transparent, and potentially disposable polymer sheet has been developed at Johannes Kepler University Linz (Linz, Austria). "To our knowledge, we are the first to present an image sensor that is fully transparent--no integrated microstructures, such as circuits--and is flexible and scalable at the same time," says Oliver Bimber, one of the two researchers. The new imager uses fluorescent molecules to capture incoming light and channel a portion of it to an array of sensors framing the sheet. With no electronics or internal components, the imager's design makes it ideal for a new breed of imaging technologies, including user-interface devices that can respond not to a touch, but merely to a simple gesture.
