| Abstract: | The optical fiber remote system for measuring gas concentration by differential absorption method is described. Furthermore, the measurement is realized for NO2 concentration in the visible region and CH4 concentration in the near infrared spectrum. The other gas molecule concentration such as atmosphere and industry pollution can be measured in a similar way. |
