- Within tissue, photons interact with biological matter via various processes, which can be broadly categorized into scattering and absorption (Fig. 1a and Box 1). Scattering can alter the propagation path, polarization and spectrum of scattered light. The states of the scattered light can be analysed and mapped for diagnosis and imaging.

Light has some interesting properties, many of which are used in medicine: 1- The speed of light changes when it goes from one material into another. The ratio of the speed of light in a vacuum to its speed in a given material is called the index of refraction. 2- Light behaves both as a wave and a particle. As
Sep 1, 2013 · In this article, the authors review basic fundamental principles of light characteristics and their interaction with the target tissue. It is imperative for the practitioner to understand these concepts to deliver appropriate, efficacious, and safe phototherapeutic treatment for their patients.

Sep 22, 2021 · Light, as an electromagnetic wave, possesses several fundamental properties, which include intensity, wavelength, phase and polarisation 1, 2 (see Fig. 1a). While the former three are...
Overall, the science behind medical lasers lies in harnessing the properties of light – precisely its intensity, wavelength, and duration – to interact with tissues in a controlled and predictable manner. This sophistication not only allows for a range of therapeutic and surgical applications but also ensures greater safety and efficacy in ...
