    Abstract:

    Under the support of the national science and technology cooperation project(project number: 2014DFA11190), using self-designed optical fiber femtosecond laser, high-speed optical delay scanning device, terahertz emission and detection modules, the first portable real-time terahertz spectrometer industrial product(mode:mini-T) is successfully developed in China. Spectral width coverage of 0.1-7 THz, spectral resolution 9 GHz, waveform sampling rate reaches 500 Hz, dynamic range is better than 70 dB. It supports three measurement modes including the transmission, reflection and Attenuated Total Reflection(ATR). Using a highly-integrated design, the overall size is only 300 mm(long) ×200 mm(wide)×120 mm(high), and the weight is only 7 kg. It supports the built-in lithium batteries(continuous working hours about 2.5 h). This product can work normally in 10-40 ℃ range, and has a good vibration stability, which can meet the challenging requirements for industrial field measurement conditions, such as real-time, portable, environmental adaptability and reliability.
