| Research Abstract |
I demonstrate terahertz spectroscopic imaging of frozen tissues. The samples were frozen to -40C and the spectra were measured using a THz time domain spectrometer. The transmission image shows clear contrast originated in the water content in the tissues. I also found a difference of THz transmission spectra between rapidly frozen tissues and slowly frozen ones, which is mainly due to the difference of liquid water remaining in the tissues. In order to clarify the origin of the THz absorption, we also measured the THz transmission spectra of frozen gelatin solution, which was colored by Rhodamin B and the particle of the THz absorption was studied by comparing the absorbance of frozen tissues, freeze dried ones and ice crystals.
