Abstract

본 발명은 광학적 가스농도 계측시스템에 관한 것으로, 레이저광을 측정대상가스로 발진하는 발진부와; 측정대상가스를 통과한 레이저광을 수광하여 전기적 신호로 검출하는 수광부와; 직접흡수기법 또는 파장변조기법에 의해 측정대상가스의 초기농도를 구하고, 측정된 농도값으로부터 광흡수율이 계산되면 광흡수율과 미리 설정된 설정값의 비교를 통해 측정기법를 선택하여 측정대상가스의 농도를 측정하는 데이터분석기; 를 포함하는 것을 특징으로 하여, 측정대상가스의 광흡수율에 따라 보다 정밀한 농도측정이 가능한 기법을 자동으로 선택하여 농도측정을 수행함으로써, 보다 정밀하고 정확한 농도의 측정이 가능해지는 효과가 있다.
