A Novel Optical Oximeter via Absorption Spectra-Based CO2 Laser Photothermal Effects

Spectroscopic and histological study of CO2 laser interaction with rats tissues were carried out. We detected for the first time the changes in optical absorption spectra of rat’s tissues with selective CO2 laser optical densities ranging from 20.64 to 34.40W/cm2. The laser exposed tissues show higher absorbance in hemoglobin than that for the unexposed tissue.…
