The infrared absorbance anisotropies of (a) 1338 cm−1 at both 31.25 μm (SZ) and 300 μm (upper RZ) and (b) sugar bands at 300, 400 and 500 μm. (c) The infrared absorbance anisotropies of sugar band in the deeper RZ and calcified tissue (606.25, 637.5 and 725 μm). The mean errors of the sugar absorbance at the six depth locations from 300 to 725 μm are 9.7%, 8.4%, 6.0%, 7.5%, 9.9% and 8%, respectively.
