Abstract
A laser diode absorption system was developed to measure CO2 gas temperature and concentration using a 2.0 µm DFB (distributed feedback) laser. The optics were fabricated in a pigtail fashion, and were developed along with an optical filter and fiber ring interferometer for this wavelength were developed as a one box. The measurement sensitivity at different sweep frequencies and pre-set CO2 concentrations were evaluated using a test cell. The results showed that the system had a 2% error over a wide range of operating frequencies. Measurements of CO2 concentration were obtained close to the post flame-front of a premixed laminar flame. The instantaneous gas flame temperature measured using a 2-line absorption scheme [1] was compared to that measured by a thermocouple.
The application of the developed CO2 sensor to the measurement of exhaust gas concentration fluctuation in a practical engine was examined. The results indicate that the time variation of the absorption lines for 2 wavelengths coincided, demonstrating that the CO2 concentration variation period could be measured.
