Three-dimensional imaging through scattering media using three-dimensionally coded pattern projection

Appl Opt. 2015 Aug 20;54(24):7316-22. doi: 10.1364/AO.54.007316.

Abstract

We propose a method for visualizing three-dimensional objects in scattering media. Our method is based on active illumination using three-dimensionally coded patterns and a numerical algorithm employing a sparsity constraint. We experimentally demonstrated the proposed imaging method for test charts located three-dimensionally at different depths in the space behind a translucent sheet.
