“Recent advances in TDLAS, and especially the way a spectrum is analysed, has opened new opportunities and added functionality to combustion analysers.This article will discuss a new signal processing approach that helps extract more information than before from the acquired spectrum. The approach has been designed to help create a new path forward for smart […]

Recent developments in quantum cascade lasers have enabled the development of new sensors for in-situ applications that have so far only been possible with extractive systems. In this work, a sensor is presented using a unique Wavelength Modulation Spectroscopy approach to measure tetrafluoromethane, a strong greenhouse gas. The sensor was characterized in a laboratory environment […]
