“… 13 , 14 , 15 The contrast in ultraviolet photoacoustic microscopy (UV-PAM) arises from intrinsic light absorption, which enables high-contrast imaging of cell nuclei. 16 , 17 , 18 Nonlinear microscopy, including multiphoton microscopy and stimulated Raman scattering microscopy, can generate optical signals from different sources, such as autofluorescence emission, 19 , 20 , 21 noncentrosymmetric structures, 22 , 23 tissue interfaces with a change in refractive indices, 24 , 25 and molecular vibrations. 26 , 27 , 28 However, these scanning-based methods have limited imaging throughput and cannot meet the requirements for rapid pathological tissue assessment.…”
