Optical property measurements in mammalian cartilage

摘要

The optical properties of porcine nasal cartilage have been determined at a wavelength of 632.8 nm using two different techniques. A single integrating sphere method was used to measure diffuse reflectance and diffuse transmittance, while total attenuaion was determined from separate measurements of collimated transmission. Optical properties (absorption and scattering coefficients, and scattering anisotropy) were obtained by comparing measured results with predictions of Monte Carlo computer simulations. An estimate of the validity of the optical propeties was obtained by measuring the optical penetraion depth in bulk cartilage tissue.
