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.

OBJECTIVES

  • 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.
