Abstract:
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 ultrafast 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 of representative ultrafast imaging modalities. Then, I will focus the discussion on two research directions in my Laboratory of Applied Computational Imaging. First, I will present compressed optical-streaking ultrahigh-speed photography for the advanced characterization of rare-earth-doped nanoparticles for biomedical and information security applications [Nat. Commun. 12, 6401 (2021); Adv. Sci. 11, 2305284 (2024)]. I will also discuss how to integrate this concept with an ultrafast laser system for coded-aperture temporal imaging to >100 trillion frames per second [Nat. Commun. 15, 1589 (2024)]. Second, I will discuss how coded optical streaking can speed up single-pixel imaging to 12,000 frames per second [Nat. Commun. 13, 7879 (2022)] and allow human thermometry [Nat. Commun. 16, 8885 (2025)].
