Abstract
A method and a system for imaging a transient event, the method comprising passively recording spatiotemporal projections of the transient event in an angular range from −45° to +45°; and processing the recorded spatiotemporal projections by compressed sensing tomographic image reconstruction to recover the transient event. The system comprises an imaging unit and a shearing unit for imaging a dynamic event to different positions, a detector that records data by spatially integrating over each pixel and temporally integrating; and a processing unit that reconstructs the dynamic event from said data by compressed sensing tomographic image reconstruction.
