Vibrational spectroscopy

In coherent Raman scattering(CRS), it is generally difficult to achieve both high spectral resolution and a wide spectral coverage simultaneously. This trade-off is analogous to that in spatial imaging, where designing an objective lens that simultaneously provides high spatial resolution and a wide field of view is challenging. To overcome this limitation, a computational imaging approach known as Fourier ptychographic microscopy (FPM) has been proposed. In this study, we extend the concept of FPM to time-resolved vibrational spectroscopy and propose Fourier ptycho-spectroscopy (FPS), which enables high spectral resolution through a computational reconstruction framework.
