Combining light scatting spectroscopy (LSS) and spectroscopic optical coherence tomography (LS-SOCT) can provide a wealth of information. A theoretical model for analyzing the scattering in SOCT is proposed based on plane wave decomposition. Based on the model, we discuss the possibility of matching the physical characteristics of scatterers with observed spectroscopic signals. Many complicating factors are considered including the effects of scatterer size, incident light polarization, interference between the fields scattered from closely adjacent scatterers, and the numerical aperture of the OCT system. We found the modulation of the spectrum of the incident light by scattering of a plane wave from a single sphere is a good indicator of particle size and composition. We demonstrate that measuring wavelength-dependent scattering in SOCT can be used for particle sizing and contrast enhancement by differentiating cells in 3D cell culture.
