Femtosecond-scale phase information and intensity captured in a single shot
Experimental configuration of CST-CMFI. Fs laser: femtosecond laser; PS: pulse stretcher; BP: band-pass filter; BS: beam splitter; FROG: frequency-resolved optical gating; M: mirror; DS: dynamic scene; OL: objective lens; LP: long pass filter; L: lens; D: diaphragm; PM: phase modulator; DG: dispersive grating; CM: compressed measurement (Image: East China Normal University)
The new method has been called “compressed spectral-temporal coherent modulation femtosecond imaging (CST-CMFI)” by its developers
