CEA-Leti Announces Prototype of Next-Generation, Low-Cost Photo-Acoustic Sensors For Gas Detection And Analysis
REDFINCH Team Achieves These Capabilities in Mid-infrared Region, Where Many Important Chemical and Biological Species Have Strong Absorption Fingerprints
Leti, a research institute of CEA Tech, today announced prototype development of highly miniaturized, portable optical sensors for chemical detection of gas.
“The big picture is that the miniaturization of photo-acoustic spectroscopy based on quantum cascade lasers (QCLs) is entering the stage of mass production,” said Jean-Guillaume Coutard, an instrumentation engineer at Leti, who coordinate the project.
“This allows both the detection and concentration measurement of a wide range of gases, liquids and biomolecules,” Coutard said. “This is crucial for applications such as health monitoring and diagnosis, detection of biological compounds and monitoring of toxic gases.”
“This project is a perfect fit for mirSense’s development roadmap. Our mission is to democratize QCL usage,” said Mathieu Carras, CEO of mirSense, which participated in the project. “mirSense is ready to produce these state-of-the-art integrated QCL-based components and do a similar job on electronics and software to bring the value of this technology to the market.”
