Fig. 3: High-resolution Brillouin imaging of ex vivo porcine corneas with a 780 nm wavelength.
From: Measuring mechanical anisotropy of the cornea with Brillouin microscopy
a En-face image showing relatively uniform Brillouin value across the x–y plane. Note that the colormap scale used in this figure is different from that of Fig. 2b (due to the wavelength difference). b Brillouin images of the same corneal sample measured in cross-section at three different (relative) depths, revealing a lamellar pattern. c Larger Brillouin image of a second corneal sample measured in cross-section. d Brillouin images of a third corneal sample measured en-face at three different (relative) depths. e Brillouin images of the same (third) corneal sample measured in cross-section at three different (relative) depths. f Distribution of αxx values estimated from 31 cross-sectional Brillouin images of 7 ex vivo corneas from 7 pigs. Points displayed in the same color represent data taken at different spatial locations in the same corneal cross-section. Box-plot: center line, median; box limits, upper and lower quartiles; whiskers, range of data.
