Abstract

This paper proposes the effective compensation method fur the IR lamp deterioration in NDIR capnograph system. The newly designed optical chamber with two IR lamps and an electronic hardware for controlling lamp intensity have been implemented. After applying the proposed optical chamber and reference lamp control circuit to the NDIR type capnograph system, it is identified that the proposed method can compensate the lamp deterioration effectively.
