研究目的
To provide a unique calibration service of THz power responsivity of suitable detectors and to solve the problem of comparability of THz power measurements.
研究成果
The unique Terahertz metrology at PTB has closed the metrology gap between infrared optics and high frequency electronics in a high-tech sector at frequencies around 1 THz, bringing traceable THz measurements from the research laboratory to application in industry.
研究不足
The calibration service is limited to the spectral range from 0.7 THz to 5 THz.
1：Experimental Design and Method Selection:
The THz radiometry working group of PTB uses a molecular gas laser for calibration services.
2：Sample Selection and Data Sources:
Pyroelectric thin-film detectors are used for dissemination of the THz power scale.
3：List of Experimental Equipment and Materials:
Molecular gas laser, pyroelectric thin-film detectors, thermopile THz standard detector.
4：Experimental Procedures and Operational Workflow:
Calibration of detectors at a single THz frequency above 1 THz against the thermopile THz standard detector.
5：Data Analysis Methods:
Comparison of power responsivity of THz standard detectors of metrology institutes.
