Single-pixel imaging through turbid media by combining a programmable light source and a DMD

Abstract

Imaging through turbid media remains a relevant topic in biomedical imaging. In this contribution, we propose the combination of frequency domain imaging (SFDI) and single-pixel imaging (SPI) to image objects hidden by a turbid media. Firstly, the SFDI method allows to characterize the turbid media by projecting sinusoidal intensity patterns. Secondly, SPI technique provides images of the object through the areas of the turbid media with higher transmission of ballistic photons. The key elements of the system are a DMD to generate the sampling patterns and a LED array working as a programmable light source. Experimental results supporting this idea are shown.
