Tissue Optics: Measurement Methods

This lecture covers the measurement methods used in tissue optics, focusing on direct and indirect approaches. Direct methods involve the direct measurement of optical properties, while indirect methods rely on models to describe light propagation. The lecture explains the challenges of direct methods, such as sample degradation and heterogeneities, and the suitability of indirect methods for in vivo measurements. It also discusses the classification of indirect methods and the use of added absorbers. Various techniques like spatially resolved reflectometry and integrating sphere measurements are explored, providing insights into the experimental conditions and theoretical foundations of tissue optics.
