We present rolling shutter speckle imaging (RSSI), a single-shot temporal speckle imaging technique that can quantitatively measure the fast dynamics of scattering media without high speed cameras. Utilizing a rolling shutter image sensor and vertically elongated speckles, RSSI can quantitatively map the speckle dynamics from a single image capture. We discuss the speckle spatiotemporal intensity correlation model for RSSI, which is validated through simulations and phantom experiments. We show in vivo quantitative blood flow imaging of the mouse brain from a snapshot measurement. In addition to imaging, we also present rolling shutter speckle plethysmography for cardiovascular monitoring.
