This is the final report on the progress achieved under ARO grant to develop a novel, compact Terahertz THz spectroscopy system with and without moving parts for realtime, in-situ, rapid, and sensitive bio and condensed matter sensing. The proposed THz unit would increase the speed of measurements and improve analysis times to obtain THz spectra of biological and chemical agents as well as analysis of the absorption and refraction indices of those agents. We focused on investigating the actual THz-spectrometer with and without a grating time delay unit. The grating, by its nature, creates a natural time delay. We included a grating in a real THz device and investigated the parameters of THz pulse time delayed by the grating. After that, with the grating included in the real THz device we investigated THz spectra of real biological agents i.e. Alzheimer-Disease AD brain tissue and the Breast Cancer Cells BCC. A paper was published on AD and Normal Brain and breast cells .
