Experimental study demonstrates single-shot ultrafast compressed imaging using multi-angle spatiotemporal projection, indicating resolved spatial anisotropy in transient events.
A multi-dimensional spatiotemporal projection-based ultrafast compressed imaging technique is proposed. By incorporating a multi-angle projection module via time-wavelength mapping and two-dimensional diffraction, omnidirectional spatial frequencies of the transient event are captured to eliminate spatial anisotropy and achieve ultrafast imaging with high spatiotemporal resolutions.
