Lecture
This lecture covers the historical perspective of the quantum description of light, focusing on Max Planck's and Albert Einstein's contributions. It delves into the photoelectric effect, photon properties, wave-particle duality, and the wave mechanics behind tissue optics, including tissue optical parameters and the microscopic origin of dispersion. The interaction between light and tissues, the objectives of tissue optics, and the ultimate goal of non-invasively assessing tissue properties are also discussed.
