  • Patent number: 12250473
    Abstract: A method and a system for imaging a dynamic scene, by time-spectrum mapping when a single chirped pulse probes the dynamic scene, storing temporal information at different wavelengths, spectral shearing, spatial encoding and reverse spectral shearing; spatiotemporal integration; and image reconstruction from a resulting captured snapshot, using a laser source configured to emit a linearly chirped laser probe pulse; an imaging unit; a shearing and reversing shearing unit; an encoder; a detector; and a computer; wherein the imaging unit is configured to record the linearly chirped laser probe pulse transmitted by the dynamic scene in a snapshot; the shearing and reversing shearing unit is configured to spectrally shears the linearly chirped laser pulses received from the imaging unit to the encoder, the detector records a compressed snapshot of a temporal information of the dynamic scene read out by the probe pulse; and the computer processes the snapshot and yields a(x,y,t) datacube of the dynamic scene.
