Abstract

CW Terahertz imaging system is being constructed to investigate the response of cell to the terahertz wave. This system consists of a 0.2 THz radiation source and some off-axis-parabolic mirrors (OAPs) with 2 dimensional (2D) translation stage. Detection is achieved with a pyroelectric sensor operated at room temperature. Biological terahertz imaging of a ratpsilas paraffin-embedded epithelial cell with tumor is presented.
