| Abstract: | A new kind of the practical IR carbon dioxide and carbon monoxide gage using LiTaO_3 pyroelectric detector was presented.The principle and the structure of the gage were described.Based on Lambert-Beer law,the gage can detect carbon dioxide and carbon monoxide with high precision and efficiency.This gage involves some techniques such as optical dual-beam structure,temperature compensation for the IR detetor,data processing methods,and selecting LiTaO_3 pyroelectric detector. |
