Introduction

JJF 1071 "National Metrological Calibration Rules Writing Rules", JJF 1001 "General Metrology Terms and Definitions" JJF 1059.1 "Measurement Uncertainty Assessment and Representation" together constitute the basic series of norms developed by this specification. This specification is the first release. (0.1 ~ 2.5) THz terahertz spectrometer calibration specification

1 Scope

This specification applies to the calibration of the terahertz spectrometer in the frequency range of 0.1THz to 2.5THz.

2 terms

2.1 terahertz radiation terahertzradiation, THz Frequency in the 0.1THz ~ 10THz, the wavelength of 30μm ~ 3mm range of electromagnetic radiation. In the micro The transition between wave and infrared, also known as terahertz or terahertz. 2.2 terahertz time domain spectroscopy techniques terahertztime-domainspectroscopy, THz-TDS By measuring the time-domain waveform of the terahertz pulse electric field, the Fourier transform algorithm is used to obtain the terahertz pulse in the frequency domain Of the spectrum and phase of the technology. 2.3 terahertz echo pulse terahertzechopulse When the terahertz pulse travels through the optical element, the time domain veins are detected after the front and back surfaces of the component are reciprocated and reflected Red The terahertz echo pulse and the main pulse are delayed in the time domain and produce spectral interference in the frequency domain.

3 Overview

Terahertz spectrometer is the use of terahertz time-domain spectroscopy techniques to measure the spectral characteristics of the sample in the terahertz band, Also known as terahertz time domain spectrometer or terahertz time domain spectroscopy measurement system. The terahertz spectrometer utilizes femtosecond pulse laser excitation Transient emission of coherent terahertz radiation or the use of optical rectification in the electro-optic crystal to produce ultrashort Coherent terahertz radiation, the use of another beam of femtosecond pulse laser detection of terahertz radiation field, through the electro-optic crystal and balance Detectors for electro-optical sampling or detection using ultrafast photoconductive antennas. Change between the detection pulse and the pump pulse Time delay to obtain the terahertz time domain pulse waveform, using terahertz time domain spectroscopy to obtain frequency domain spectrum and phase. through The measured samples were interacted with terahertz radiation to measure the transmission spectra and reflectance spectra of the samples in the terahertz band Sex, resulting in refractive index and absorption coefficient, master the sample optical properties. The usual spectral measurement range for the terahertz spectrometer is 0.1 THHz to 2.5 THz. The terahertz spectrometer from the light path junction The structure is divided into transmission and reflection. Transmission and reflection of the terahertz spectrometer structure diagram shown in Figure 1 and Figure 2 shows.
