a Schematic of the sample configuration. An 800-μm-thick onion tissue was placed on top of a custom-made resolution target, and a time-gated reflection matrix was recorded with its focus and temporal gating set to the target depth. b Intensity map of confocal reflectance image. Scale bar, 30 μm. c MST image after rectifying the identified multiple scattering trajectories. Intensity maps in b, c are normalized by the peak intensity of c. d Identified phase functions, \({\varphi }_{k}^{{{{{{\rm{c}}}}}}}\left({{{{{\boldsymbol{\rho }}}}}}\right)\), at five different depths by the MST algorithm. Color bars, phase in radians.
