Paper Abstract

The optical properties of a tissue can be specified by the depth dependence of a reflectance-mode confocal measurement, as the focus is scanned down into a tissue. Reflectance-mode confocal scanning laser microscopy (rCSLM) and optical coherence tomography in focus tracking mode (OCT) are two examples of such confocal measurements. The measurement of reflected signal as a function of the depth of focus, R(z), is expressed as ρe-μz, where ρ [dimensionless] is the local reflectivity from the focus within a tissue and μ [cm-1] is the attenuation of signal as a function of z. The reflectivity of a mirror defines ρ = 1. This paper describes how the experimental ρ and μ map into the optical properties of scattering coefficient, μs [cm-1], and anisotropy of scattering, g [dimensionless]. Preliminary results on tissue for the rCSLM and OCT systems are reported.
