I4.3 - Design and Simulation of a NDIR Gas Sensor System with Ray Tracing Using a Monte-Carlo Method

Johann Mayrwoeger, Peter Hauer, Bernhard Jakoby, Wolfgang Reichl & Christian Krutzler
NDIR-gas sensors consist of basic building blocks, i.e., an IR-source, an optical path containing the sample gas, a filter, and an IR-detector. Every single part affects the behavior of the whole system. To minimize development time and costs, we investigate an efficient approach to simulate the entire sensorsystem in the beginning of the design process such that the most promising designs can be rapidly identified and pursued in the subsequent prototype engineering phase. For the...
