- Abstract
Quantitative measurements of scattering properties are invaluable for optical techniques in medicine. However, noninvasive, quantitative measurements of scattering properties over a large wavelength range remain challenging. We introduce low-coherence spectroscopy as a noninvasive method to locally and simultaneously measure scattering sand backscattering bcoefficients from 480 to 700 nm with 8 nm spectral resolution. The method is tested on media with varying scattering properties (s 1 to 34 mm−1and b 2.10−6to 2.10−3mm−1), containing different sized polystyrene spheres. The results are in excellent agreement with Mie theory.
