| Introduction | A method for ultrafast time-resolved digital holography comprises (a) providing tunable timescale at least two tick-tock pulses arriving on a sample to be measured at various timescales, (b) spatial encoding for wavefronts of the sample by utilizing at least one optical encoder, (c) utilizing a digital holographic access unit to record a composite hologram of the spatial encoded wavefronts by the same single pulse source, (d) utilizing an encoder for obtaining at least two holograms, and (e) utilizing a compressive sensing approach or a non-linear image restoration approach and a wavefront reconstruction approach to obtain the reconstructed wavefronts information of the sample. |
