Light interaction with tissues can be described in several ways:
Absorption: Different tissues absorb light at varying degrees based on their composition. For instance, melanin absorbs more light, making pigmented tissues appear darker. Reflection: Some of the light hitting the tissue surface bounces back, which can affect the visibility of certain structures. Refraction: Light bends as it passes through tissues of different densities. This bending can create distortions but also helps in focusing. Transmission: Light that passes through tissues can provide information about the internal structure based on how much light is transmitted.
