Abstract

Disclosed herein are systems and methods of phase-sensitive compressed ultrafast photography (pCUP). In some embodiments, a pCUP system comprises: a dark-field imaging system, and a compressed ultrafast photography (CUP system). The dark-field imaging system may comprise a laser source configured to illuminate the subject with a laser pulse; and a beam block configured to pass laser light scattered by the subject as a first series of phase images and block laser light not scattered by the subject. The CUP system may comprise: a spatial encoding module configured to receive the first series of phase images and to produce a second series of spatially encoded phase images; and a streak camera configured to receive the second series of spatially encoded phase images, to deflect each spatially encoded phase image by a temporal deflection distance, and to integrate the deflected phase images into a single raw CUP image.
