The application of industrial CO monitoring based on infrared imaging molecular filter technology

The development of imaging equipments for pollutant gases monitoring is concerned not only to efficient resource utilization but also to environment protection. CO is extremely harmful although its concentration is relatively low among industrial waste gases, which leads to a challenge for traditional spectral remote sensing methods. The infrared imaging molecular filter show great advantage in extracting target gas infrared spectrum signal and restraining radiation interference from environmental background and other gases due to its characteristics of the comb like transmission spectrum with ultra narrow band. In this paper, remote sensing and monitoring of industrial CO emissions based on infrared imaging molecular filter technology is carried out. real-time images of CO gas are also obtained. The experimental results show that this scheme provides a good solution for remote sensing and monitoring of industrial waste gas by using an imaging method.
