| Stakes
CEA-Leti has designed and built integrated beam combiners for three different wavelength domains based on the specifications agreed between the project partners.
One beam combiner is dedicated to a monitoring system working at nine specific wavelengths around 3.4 μm, one is dedicated to a continuous spectral domain around 6.8 μm and the more prospective third is dedicated to a large spectral domain around 9 μm.
CEA-Leti has also built, tested and delivered an ASIC capable of driving the QCL array and is now producing a modified version of this ASIC for the ICL array.
Real-time measurements of multi-components in process streams respond to long demanded industry requirements for fast, accurate, reliable and cheap process analyzers. Growth of these currently unavailable systems will lead to a paradigm change throughout the process control and production chain. The iCspec project is focusing on developing compact, robust, maintenance-free sensors for fast, in-line, multi-species measurement of chemical composition for process analytics involving multiple technically relevant gases including hydrocarbons. The projected sensors will replace expensive, polluting, state-of-the-art systems. Established laser-based, in-line gas sensing is being extended to the mid-infrared “chemical fingerprint” spectral range for multi-species detection.
Project developments are based on two key operations: (1) Integration of mid-IR laser arrays and, (2) Advancement of spectroscopic and chemometric data evaluation. Demonstrators are integrated into the control loop at a petro-chemical plant allowing significant improvements including optimized product quality, minimized waste, reduced environmental pollution and greater safety in cases, in which hazardous conditions need to be immediately detected.
IMPACT
AirOptic now commercializes a monitoring system based on the iCspec results.
