报告题目:Coded Optical Streaking for Real-time Ultrahigh-Speed Imaging



Visualizing transient events in the durations of their occurrences (i.e., real time) is indispensable to understanding many physical, chemical, and biological processes. Among existing methods, real-time ultrahigh-speed imaging based on coded optical streaking has received increasing attention because of its high image quality, high adaptability, and broad applicability. In this talk, I will review the working principles and limitations in representative ultrahigh-speed imaging modalities. Then, I will focus the discussion on three research directions in my Laboratory of Applied Computational Imaging in the past three years. First, I will present compressed optical-streaking ultrahigh-speed photography for the advanced characterization of rare-earth-doped nanoparticles for optical thermometry [Nat Commun 12, 6401 (2021); IEEE J Selected Top Signal Process 16,688 (2022)]. Second, I will discuss how coded optical double-streaking can speed up single-pixel imaging [Nat Commun 13, 7879 (2022)], which enables multi-spatiotemporal-scale visualization in different modes and under the high-ambient-light environment at up to 12,000 frames per second. Finally, I will show how the dynamic optical diffraction, generated by the microsecond transition between two masks loaded onto a programmable grating, can be used as a new gating mechanism for ultrahigh-speed mapping photography [Optica 10, 1223 (2023)].
