    摘要: System and method for spatially and spectrally parallelized FAST. A sample is illuminated to thereby produce interacted photons. The photons are passed through a filter and received at a two-dimensional end of a FAST device wherein said FAST device comprises a two-dimensional array of optical fibers drawn into a one-dimensional fiber stack so as to effectively convert a two-dimensional array of optical fibers into a curvilinear field of view, and wherein said two-dimensional array of optical fibers is configured to receive said photons and transfer said photons out of said fiber array spectral translator device and to a spectrograph through said one-dimensional fiber stack wherein said one-dimensional fiber stack comprises at least two columns of fibers spatially offset in parallel at the entrance slit of said spectrograph. The photons are then detected at a detector to thereby obtain a spectroscopic data set representative of the sample.
