Phase-sensitive compressed ultrafast photography systems and methods

A phase-sensitive compressed ultrafast photography (pCUP) system for obtaining a series of final recorded images of a subject, comprising:

• a dark-field imaging system, the dark-field imaging system comprising:
• a laser source configured to illuminate the subject with at least a first laser pulse for an imaging duration;
• and
• a beam block configured to pass laser light scattered by the subject upon illumination by the first laser pulse as a first series of phase images and block laser light not scattered by the subject;
• and
• a compressed ultrafast photography (CUP) system configured to receive the laser light scattered by the subject and passed by the beam block, the CUP system comprising:
• a spatial encoding module configured to receive the first series of phase images and to produce a second series of spatially encoded phase images, each spatially encoded phase image of the second series comprising at least a first view including one phase image of the first series of phase images superimposed with a pseudo-random binary spatial pattern;
• and
• a streak camera coupled to the spatial encoding module, the 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 that varies as a function of time-of-arrival, and to integrate the deflected phase images into a single raw CUP image.
