The quantitative analysis of spectral domain optical coherence tomography was researched to acquiring interior information of biological tissues.The single-scattering model
confocal single-scattering model and multiple-scattering model were presented and discussed. An average A-scan algorithm and a nonlinear curve-fitting method were employed to explore the scattering features of Intralipid
