Abstract

Compressed ultrafast photography (CUP) is a novel computational imaging modality that synergizes compressed sensing with streak imaging. In data acquisition, a transient spatiotemporal (x,y,t) scene is compressively recorded in a single snapshot by successively going through spatial encoding, temporal shearing, and spatiotemporal integration. In movie reconstruction, a compressed-sensing reconstruction algorithm is employed to recover the datacube of the transient event. Compared with pump-probe ultrafast imaging schemes, CUP is capable of single-shot, receive-only, ultrafast imaging of non-repetitive or difficult-to-reproduce transient events. Compared with other single-shot ultrafast imaging techniques, CUP does not require specialized active illumination and possesses high light throughput.
