The analytical model that took Texas A&M University biomedical engineer Lihong Wang six months to develop solves a long-standing mystery in the field of acousto-optics, a branch of physics dealing with the interaction of high-frequency sound waves (ultrasound) and coherent (laser) light.

"We've known for over half a century about the mechanism of acousto-optics in clear media. Its counterpart in scattering media, however, was a mystery," said Wang, an associate professor in the Department of Industrial Engineering's biomedical engineering...
