Abstract
We demonstrate a simple method for realizing STAMP (Sequentially Timed All-optical Mapping
Photography) in a compact 4f configuration utilizing spectral filtering: STAMP utilizing Spectral
Filtering (SF-STAMP). SF-STAMP system consists of a diffractive optical element (DOE), a band-pass
filter (BPF), and two Fourier transform lenses. SF-STAMP system works as a single-shot multispectral
imaging system. Using a linearly frequency-chirped laser pulse, ultrafast 2D-burst imaging is realized.
The number of multispectral images captured by a single shot is determined by the DOE, which is 25 in
our current system. We capture ultrafast phenomena with sub-picosecond temporal resolution using a
frequency-chirped Ti:sapphire laser pulse.
