We developed photoacoustic tomography to peer deep into biological tissue. Photoacoustic tomography (PAT) provides in vivo omniscale functional, metabolic, molecular, and histologic imaging across the scales of organelles through organisms. We also developed compressed ultrafast photography (CUP) to record 10 trillion frames per second in real time, orders of magnitude faster than commercially available camera technologies. CUP can capture the fastest phenomenon in the universe, namely, light propagation, at light speed and can be slowed down for slower phenomena such as combustion.
