The project has successfully developed an isotope on-line measurement system based on the wavelength-modulated off-axis integrated cavity output spectrum technology with independent intellectual property rights, which has broken through the development of online frequency-locked, long-path passive cavity resonators for laser output, and optical path adjustment, algorithm resolution, and temperature Key technologies such as precise pressure control have increased the independent innovation ability and core competitiveness of the project team in the field of laser spectroscopy. At present, the project team has developed 3 sets of prototypes during the project period, and has conducted demonstration demonstrations on the air environment monitoring, coal mine gas traceability, and greenhouse gas emission sources and sinks in real-time monitoring of atmospheric environmental pollutants in China. And precise analysis provides new technical means.

The test expert group reviewed the test syllabus for various technical indicators of the implementation plan, and conducted field tests on various technical indicators of the monitoring system; the acceptance expert group reviewed the relevant acceptance materials provided by the project team and heard the person in charge of the project. The work report, financial report and test report of the test team verified the operation of the equipment. After questioning and discussion, they unanimously held that the project completed the various mission objectives, assessment objectives and technical indicators specified in the implementation plan, and agreed that the project passed acceptance. .
