Seeing through turbid fluids: a new perspective in microfluidics

Optical imaging through turbid media has many potential uses, from homeland security to microscopic particle research. In 1967, Stetson conducted pioneering work on holography for imaging through scattering media. Years later, Lohmann et al. used holography to see through fog. These studies and others have become more relevant since microfluidic technology and lab-on-chip devices were developed.
