THz Spectroscopy, Holographic Approach and Phantoms Design for the Diagnostics of Socially Significant Diseases

This work describes the promising approach for the diagnostic of diseases, such as diabetes, by using the THz spectroscopy and THz holography method. In this paper, dry pellets consisting of human blood plasma (normal and diabetic) were designed; these objects were analyzed in various THz Russian laboratories, PCA-analysis of THz spectra was applied to separate the normal and diabetic groups; the holographic approach was proposed that provides sufficient information to reconstruct the spatial distribution of complex refractive index of the samples.
