Spectral-volumetric compressed ultrafast photography simultaneously captures 5D information in a single snapshot.

Information-rich optical imaging can provide multidimensional information to enable observation and analysis of a detected target, contributing insights into mysterious and unknown worlds. With its ability to capture dynamic scenes on picosecond—and even femtosecond—timescales, ultrafast multidimensional optical imaging has important applications in the detection of the ultrafast phenomena in physics, chemistry, and biology.

While pump-probe-based ultrafast imaging can acquire high-resolution multidimensional information, it cannot adequately capture unstable or irreversible transient scenes. Fortunately, compressed ultrafast
