Photon migration

Photon migration refers to the movement of light particles, called photons, as they travel through a medium like tissue or other materials. When light enters such a medium, it doesn't just pass straight through; it scatters, reflects, and is absorbed, changing direction and intensity. This process helps scientists and doctors understand the properties of the medium, such as detecting abnormalities in tissue or measuring blood flow. Essentially, photon migration models how light interacts with complex structures, providing valuable information about what's happening inside objects without invasive procedures.
