  We demonstrate an approach that allows taking videos at very high-speeds of
over 100,000 frames per second (fps) by exploiting the fast sampling rate of
the standard rolling-shutter readout mechanism, common to most conventional
sensors, and a compressive-sampling acquisition scheme. Our approach is
directly applied to a conventional imaging system by the simple addition of a
diffuser to the pupil plane, randomly encoding the entire field-of-view to each
camera row, while maintaining diffraction-limited resolution. A short video is
reconstructed from a single camera frame via a compressed-sensing
reconstruction algorithm, exploiting inherent sparsity of the imaged scene.
