摘要： Infrared spectroscopy can provide fingerprints of most molecular compounds, which is widely used for detection of solid, liquid, and gas components with the advantages of fast response, high sensitivity, and specificity. However, Fourier transform infrared spectroscopy (FTIR) system has a large size and is heavy in quality, which limits its potential for onsite detection applications. With the development of materials and technology, quantum cascade laser (QCL), as a kind of infrared coherent light source, has gradually appeared on the market, which provides the possibility to design a portable infrared spectroscopy system with the features of light weight and low cost. Therefore, based on the miniaturized QCL and infrared detector, we designed a portable infrared spectroscopy detection system with a bandwidth of 200 cm(-1) (1168952 cm(-1)) in this paper. We successfully detected the infrared absorption characteristic peak of ethanol gas at 1060 cm(-1) with this system, which verified its feasibility for detecting infrared spectroscopy of molecular compounds.
