摘要

The experimental data on CO_2 detection in atmosphere using Fabry-Perot technique are presented. The optical setup consists of two channels. Channel one measure the total reflected light, whereas channel two uses a solid substrate Fabry-Perot etalon to restrict measurement to light in CO_2 absorption bands. The free spectral range of the etalon is calculated to be equal to the almost regular spacing between the CO_2 spectral bands located near 1.58μm, where CO_2 absorption is significant. The ratio of the intensities detected by the two channels is then sensitive to CO_2 change. We are exploiting the temperature dependence of the index of refraction of the optical media to align the pass bands of the Fabry-Perot etalon to the appropriate CO_2 absorption lines. The experimental data presented show excellent agreement with our theoretical expectations. They are recorded at different gas pressures and temperatures. Some of the major advantages of the optical setup are its compactness, high sensitivity, high signal-to-noise ratio, and stability.
