This specification is the first release.
Radiation type terahertz power meter calibration specification
1 Scope
This specification applies to the frequency of 0.1THz ~ 10THz, power in the range of 0.1mW ~ 3mW radiation type too
Calibration of Hertz Power Meter. Other frequency bands and power ranges of power meters can be implemented with reference to this specification.
2 terms
2.1 terahertz radiation; terahertzradiation; THzradiation
Frequency in the 0.1THz ~ 10THz range of electromagnetic radiation, the corresponding wavelength of 30μm ~ 3mm. Terahertz radiation
Frequency in the microwave and infrared convergence transition interval, also known as terahertz wave or terahertz radiation.
3 Overview
Radiation type terahertz power meter is used to measure the terahertz radiation power of the instrument, usually by the terahertz power meter probe
And display instrument composed of two parts, the structure shown in Figure 1. Its working principle is the terahertz power meter probe suction
Receiving terahertz radiation, through the sensor will be terahertz radiation power signal into electrical signals, by the display instrument
Shows the measured terahertz power value.
