Abstract :
We developed automatic scanning GaP continuous wave terahertz Signal Generator and Spectrometer. The features of the spectrometer are higher resolution, wider dynamic range, higher measurement speed, smaller size, easier operation, easier maintenance, and lower cost compared with the spectrometer using pulse-type THz Signal Generator as a light source.
