Optical Properties of Biological Tissue in the THz Radiation Regime
Optical Properties of Biological Tissue in the THz Radiation Regime
This Demonstration shows optical properties of biological tissue in the THz frequency region. Response of tissue to THz radiation is highly dependent upon the characteristics of the THz radiation source. The theory of tissue response to a THz radiation regime is still not fully developed. We describe some theoretical calculations of the interaction of THz radiation with biological tissue. We also consider absorption and scattering of radiation in the study of some tissue properties. You can select physical parameters such as refractive index, absorption, scattering coefficients, and optical depth as well as the specific absorption rate (SAR), intensity, and dispersion of THz radiation.
Inhomogeneous tissues with high absorption and low scattering are difficult to study. Excitation resonance might occur, as indicated by a broad absorption spectrum.
