Abstract

The Spatial-frequency dependence of turbid media reflectance encodes both optical properties and depth information. The high spatial frequency domain imaging (HSFDI) can, in particular, extract key characteristics of the phase function of the scattering medium which carries the ultimate structural information of the medium. We first outline the principle of HSFDI and then present here a compact optical configuration integrating the modulated illumination and imaging systems, facilitating quantitative wide-field optical properties mapping at high spatial frequencies. The performance of HSFDI is assessed on both tissue phantoms and in vivo.
