中文摘要:
      采用自主设计的光纤飞秒激光器、高速光学延时扫描机构、太赫兹发射和探测模块,成功研制国内首台便携式实时太赫兹光谱仪工业产品(型号:mini-T)。光谱宽度覆盖0.1~7 THz,频谱分辨力9 GHz,波形采样速率达到500 Hz,动态范围优于70 dB,支持透射式、反射式和衰减全反射3种测量模式。采用高度集成的一体化设计方案,整机尺寸仅300 mm×200 mm×120 mm,质量仅7 kg,支持内置锂电池工作(连续工作时间约2.5 h)。本产品能够在10~40℃环境温度范围内正常工作,并且具有良好的振动稳定性,可满足工业现场测量条件对太赫兹光谱仪实时性、便携式、环境适应性和可靠性的苛刻要求。
英文摘要:
      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.
