The project is devoted to development of a deep optical imaging technique overcoming the blurring effect due to the high light scattering in biological tissues.  A spatial angle filter (SAF) has been invented. The recent generation of SAF facilitates a significant increase of the sampling/interrogated volume by 2-3 folds in tissues, which highly scatters light, such as skin. As the SAF technology does not require any mechanical/scanning or extra computational facilities, it can provide stable imaging collection in real time (live imaging). To date, to the best of our knowledge, there are no technologies on the market that facilitate deep skin imaging scanning with such high resolution at so low cost. Douplik’s group currently works on developing a compact skin scanner probe, similar to ultrasound probe, that can facilitate a quick cancer screening. A prototype implementation and experimental results of increasing sampling/interrogated volume by 2-3 folds in tissue intralipid phantoms can be seen in the pictures.
