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.
