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.

Abstract: Compressed ultrafast photography (CUP) techniques that produce spatially encoded images from a first series of images where each spatially encoded image has first and second views of an image of the first series of images superimposed with a pseudo-random binary spatial pattern, that transform the first view and/or the second view such that the first view is rotated 180° relative to second view, that deflect each spatially encoded image by a temporal deflection distance that varies as a function of time-of-arrival, and that integrate the spatially encoded images into a CUP image.
