Immersion effects in tissues

摘要

The refractive index matching (immersion) of components of a highly scattering tissue has been studied. The influence on tissue optical transmittance, reflectance, polarization and correlation properties of the scattered light is examined. Experimental ata for in vitro, ex vivo, and in vivo studies of various solutions, gels and oils action on optical properties of human tissues (human skin, sclera of the human eye, and blood) are presented. The dynamics of tissue optical properties depending on matter diffusion rate within tissue is studied. The possible application of immersion effect for tissue spectroscopy, imaging, and thermotherapy is discussed.
