Lensless IR spectral microscope identifies cancer

Scientists in France have demonstrated a lens-less infra-red spectral-imaging system for medical diagnostics, obtaining simultaneously morphological and biochemical information. Images at different wavelengths differentiate tumour cells “The combination of a set of lasers and lens-less imaging with an uncooled bolometer matrix allows biochemical mapping over a wide field of view,” said Grégoire Mathieu of Grenoble ...
