Figure |Working principles of ultrafast dual-modal microscopy and spatiotemporal imaging results.  (a)  Optical system principle of the dual-modal ultrafast imaging technique. The red indicates the pump light (at 800 nm), while the violet represents the probe light (at 400 nm). A delay line controls the optical path difference between the two beams.(b) Imaging procedure overview. Inverse Fourier transforms are applied to the 0th and +1st orders of the original image's Fourier spectrum to obtain dual-modal imaging results for reflectivity and topography.(c) Dual-modal spatiotemporal imaging of the dynamics of LIPSS formation on a silicon surface irradiated by different shots of cross-polarized pulse pair.
