The range of range of Brillouin shift values for various tissues. The brain (C: cortex, P: putamen, CC: corpus callosum, H: hippocampus), muscle, skin, and cartilage (S: superficial, T: transitional, D: deep) data were obtained in this work. Literature data were used for porcine retina (B, basal: nerve fiber layer, retinal ganglion cell layer, inner plexiform layer; A, apical: inner nuclear layer, outer plexiform layer, P, photoreceptor cell layer: outer nuclear layer, photoreceptor inner segment, photoreceptor outer segment) from Ref. [60]; human cornea from Ref. [39]; human crystalline lens from Ref. [61].
