Fast wide-field upconversion luminescence lifetime thermometry enabled by single-shot compressed ultrahigh-speed imaging
Abstract
Photoluminescence lifetime imaging of upconverting nanoparticles is useful for optical thermometry, but is limited for dynamic samples. Here, the authors present a wide-field and single shot approach based on compressive sensing, for video-rate upconversion temperature sensing of moving samples.
