Elastic scattering spectroscopy and optical coherence tomography

Abstract

Elastically scattered light contains information about the scattering medium with which it has interacted. The elastic scattering process can be interpreted as a change in the momentum of light due to its interaction with a scattering object. By analyzing this change in momentum, structural information such as the size, shape, and organization of scattering objects can be recovered. Recently, light–scattering techniques have been developed for examining biological cells and tissues both in the laboratory and the clinic. These techniques are broadly termed elastic scattering spectroscopy (ESS).
