Abstract

Merging the cutting-edge metaphotonics and the compressive sensing technology, we demonstrate a compact single-shot imaging system enabled by a space-time encoding metasurface - an artificially engineered synthetic surface consisting of nanometer-sized elements that can locally manipulate the time delays of incoming light at the femtosecond scale - for capturing the dynamic properties of ultrafast phenomena and uncovering the unknown or hidden laws that govern such dynamics.
