Abstract
Integrated cavity output spectroscopy (ICOS) is a technique used for high sensitive measurement of absorption spectra. In this paper,we introduced the principle of ICOS measurement technology. By analyzing the theory of ICOS technology to effectively absorb the increase of optical path length, get the relationship of the specular reflectance and the selection for the length of cavity to the stability of cavity and detection sensitivity in the designing of experimental facility. We introduced the application of ICOS technology in atmospheric monitoring, medical testing, and industrial process and so on, summed up the role of wavelength modulation and off-axis incidence combined with ICOS on noise suppression. We summed up the advantages and disadvantages of ICOS technology in trace gas detection. At the end of the paper, the trend of ICOS technology was analyzed.
