Abstract

The use of diodes instead of lasers was recently suggested for phototherapeutic applications. This trend is due to economical and practical reasons and is based on the argument that lasers have no preference over diodes as light sources as the former lose their coherency upon penetrating biological tissues. This module supports this claim while providing a brief explanation to non professionals on the meaning of coherence of light as well as the physics behind the generation of speckle patterns, and the relation of these physical entities to photomedicine.
