We propose and experimentally demonstrate a new method called SF-STAMP for sequentially timed all-optical mapping photography (STAMP) that utilizes spectral filtering. is composed of diffractive optical element (DOE), band-pass filter, two Fourier transform lenses. Using linearly frequency-chirped pulse converting the wavelength to time axis, we realize single-shot ultrafast burst imaging. As an experimental demonstration SF-STAMP, monitor dynamics laser ablation using broadband (>100 nm) temporally stretched up ~40 ps. This imaging expected be effective investigating in diverse range fields, such as photochemistry, plasma physics, fluidics.
