摘要： A method and a system method for real-time wide-field dynamic temperature sensing of an object, the method comprising producing wide-field illumination to upconverting nanoparticles at the object plane, collecting a light emitted by the upconverting nanoparticles, dividing a collected light into a reflected component and a transmitted component; imaging the reflected component into a first image, imaging the transmitted component into a second image; processing the images; and reconstruction of the object from resulting proceed images.

摘要： A system and a method for single-shot compressed optical-streaking ultra-high-speed imaging, the system comprising a spatial encoding module spatially encoding the transient event with a binary pseudo-random pattern into spatially encoded frames; a galvanometer scanner temporally shearing the spatially encoded frames; and a CMOS camera receiving the temporally sheared spatially encoded frames, during one exposure time of the camera, for reconstructing the transient event. The method comprises spatial encoding a transient event; temporal shearing resulting spatially encoded frames of the event, spatio-temporal integration, and reconstruction.
