| Outline of Final Research Achievements |
Terahertz spectrometers, which measure transmittance and reflectance of a sample by referring to the linearity of a terahertz wave sensor, are widely used in recent years. In order to support the applications of terahertz waves, the linearity self-calibration system for terahertz wave sensors was developed in this research. This system verifies the linearity of the response of a terahertz sensor to a simple summation of terahertz wave signals based on the superposition method.
In this research, the self-calibration system was uniquely constructed by combining wire-grid polarizers. Using this system, a commercial terahertz wave power meter was calibrated, and the nonlinearity of approximately less than 1% was obtained. This result is expected to be a foundation that supports the application of terahertz waves.
