[Figure 4] (IMAGE) Institute for Basic Science Caption Aberration-free volumetric image of mouse brain taken by compressed time-reversal matrix microscopy. (a) Imaging configuration. For 3D imaging of a mouse brain, a small number of speckle images are taken while continuously illuminating uncontrolled dynamic speckle patterns and moving the sample stage along the vertical direction. (b) 3D image of the mouse brain reconstructed from a compressed time-reversal matrix. (c) Representative section images before and after aberration correction and corresponding pupil aberration maps. (d) line profiles of a myelinated fiber before and after aberration correction.
