ABSTRACT
Optical imaging uses the interaction between light and tissue to probe tissue morphology and functions. Compared to other medical imaging techniques, optical imaging is noninvasive, has a very high resolution at the cellular level, and has biochemically specic contrast from light absorption, scattering, and uorescence. It provides critical information about the morphology of cells and extracellular matrix and the anatomy and physiology of tissues. Optical imaging has found many applications in medicine and is very useful in the early-stage diagnosis of diseases and monitoring the treatment outcomes.
