Characterizing Depth Resolution and Range of a Swept-Source THz OCT

An injection seeded terahertz (THz) parametric generator (is-TPG) is a high power and widely tunable THz-wave source which is promising instrument for a swept-source THz coherence tomography. In this paper, the depth resolution and the depth range are characterized using a narrow-linewidth is-TPG. The resolution of 0.2 mm is obtained in measurement and the depth range of 15 mm is calculated.
