New Scientist: Jeppe Seidelin Dam and colleagues at the Technical University of Denmark in Roskilde are developing a device that can convert IR radiation into visible light. Attached to a digital camera fitted with an IR flash, it could detect tumors by recording the telltale pattern of IR light they reflect. “This would allow a surgeon to quickly determine if the entire tumor has been removed before finishing an operation,” he says. Their results have been published in Optics Letters.
