Abstract :
The noise characteristics of terahertz (THz) signals measured by terahertz time-domain spectroscopy (THz-TDS) system are investigated experimentally. Our experimental results indicate that the signal noise is not proportional to the THz strength, but proportional to the first derivative of THz strength.
