Determination of optical properties by measuring intensity distribution in tissue sample / 国际生物医学工程杂志

ABSTRACT

Objective To design a new method of determining optical properties of biological tissue by measuring light intensity distribution.Methods The light distribution in Intralipid-10％ suspension at 650 nm was measured by optical fiber probe.The optical parameters were derived from nonlinear regression of the diffusion equation for intensity.The distribution and anisotropy of intensity was abtained by the determined optical parameters and the diffusion equation for intensity.ResultsThis new method was feasible by comparing the experimental data with published results.ConclusionThe experiment results would provide useful information for radiative transfer equation,marine optical remote sensing measurement and laser therapeutic applications.-
