Introduction to biophotonics

Section 1. What is biophotonics?

Biophotonics is concerned with the use of light, in the visible and near-visible range for purpose of studying biological tissue, cells and molecules. Biophotonics is responsible for the development of techniques which complement the range of existing imaging and therapeutic techniques in widespread clinical use. Biological tissue’s intrinsic sensitivity to light, due to elastic and inelastic interactions, combined with the development of the laser, optical components and sophisticated detectors have enabled the field to develop.
