Paving the way for cheaper infrared cameras
Researchers led by the ARC Centre of Excellence for Transformative Meta-Optical Systems (TMOS) at the University of Melbourne have developed an innovative optical screen capable of converting invisible infrared light into sharp visible images over 1,000 times brighter than previously achievable. Utilising (in part) the precision capabilities at the Melbourne Centre for Nanofabrication (MCN), the team engineered a compact flat-band dielectric metasurface paired with upconverting nanoparticles to capture and concentrate infrared light, offering a detector-free, scalable alternative to expensive semiconductor detectors and bulky thermal imaging equipment.
