Publikováno v: Medical Laser Applications and Laser-Tissue Interactions VII.

The interaction of light with biological materials, such as fruits and vegetables, is a complex process which involves both absorption, and scattering events at different scales. Measuring the optical properties of a fruit allows understanding the ph
