Abstract

A mid-infrared (IR) source at ∼ 3 μm radiation is used as a probe to measure hydration in porcine cornea. Since the Er(3+):YAG emission targets vibrational modes (around 3300 cm(-1)) in the H2O molecule, it is highly sensitive to changes in water content in the first ∼ 10 μm of the corneal tissue.
