This paper demonstrates that single pixel imaging can reconstruct polarimetric images through scattering media, extending imaging depth beyond previous limits, with experimental validation up to twice the scattering mean free path.

Contribution

It introduces a theoretical model and experimental method for polarimetric imaging through scattering media using single pixel techniques, surpassing previous depth limitations.

Findings

Successful reconstruction of Mueller matrix of hidden objects

Imaging depth extended to twice the transport mean free path

Experimental validation with scattering phantoms

Abstract

Polarimetric imaging can provide valuable information about biological samples in a wide range of applications. Detrimental scattering however currently limits the imaging depth of in-vivo imaging to approximately 1 transport mean free path. In this work, single pixel imaging is investigated as a means of reconstructing polarimetric images through scattering media. A theoretical imaging model is presented and the recovery of the spatially resolved Mueller matrix of a hidden test object is demonstrated experimentally for scattering phantoms with thicknesses up to twice the transport mean free path.
