Abstract
A system and a method for single-shot compressed optical-streaking ultra-high-speed imaging, the system comprising a spatial encoding module spatially encoding the transient event with a binary pseudo-random pattern into spatially encoded frames; a galvanometer scanner temporally shearing the spatially encoded frames; and a CMOS camera receiving the temporally sheared spatially encoded frames, during one exposure time of the camera, for reconstructing the transient event. The method comprises spatial encoding a transient event; temporal shearing resulting spatially encoded frames of the event, spatio-temporal integration, and reconstruction.

A system for single-shot compressed optical-streaking ultra-high-speed imaging, comprising:
- a spatial encoding module;
- a galvanometer scanner;
- and
- a CMOS camera;
- wherein said spatial encoding module is configured for spatially encoding the transient event with a binary pseudo-random pattern, yielding spatially encoded frames, said galvanometer scanner temporally shearing the spatially encoded frames of the transient event, and said CMOS camera receiving the temporally sheared spatially encoded frames, in one exposure of the camera, for reconstructing the transient event.
A method for single-shot compressed optical-streaking ultra-high-speed imaging, comprising spatial encoding a transient event;
- optical temporal shearing resulting spatially encoded frames of the event, thereby creating an optical streak image, spatio-temporal integration, and reconstruction.
