Experimental demonstration of imaging hidden targets in turbid media using single-shot multiview images with advanced image processing

Imaging through scattering media such as biological tissue is challenging due to the multiple scattering of light which severely degrades image quality and obscures hidden objects. This work experimentally validates an approach for imaging objects embedded within scattering media by combining multiview optical setup, based on lens array, and various image processing techniques. Experiments were carried out in transmission mode upon targets of different geometric shapes embedded within different turbid environments. Different setup conditions such as medium turbidity, target shape, illumination state, and image processing were tested and compared. A quantitative image quality metrics including contrast-to-noise ratio, signal-to-noise ratio, contrast, and visibility were adopted to evaluate the quality of the reconstructed targets. Results indicate an effective performance of the proposed methodology for imaging in turbid media.
