Remote Sensing of Gases Using Infrared (IR) Sensors

Researchers from Universidad Carlos III de Madrid, within the Infrared Sensors Laboratory (LIR), have developed multi- and hyperspectral infrared (IR) analysis techniques for the remote sensing of gases. The technology enables the design of application-specific IR sensors capable of determining both the presence of gases and their concentration without direct contact.

This solution can detect a wide range of gases relevant to industrial, environmental, and safety contexts, including CO₂, CO, NO₂, O₃, hydrocarbons, and NH₃, among others. By enabling remote and non-intrusive monitoring, the technology is particularly suitable for environments where continuous, reliable gas detection is required.

The innovative value lies in its capability to measure spectral distribution, allowing the acquisition of quantitative data on gas composition. The use of multi- and hyperspectral IR detection improves performance in quantitative analysis and enhances the identification of specific gases within complex mixtures. These features provide more accurate and robust monitoring compared with conventional single-band detection approaches, supporting better decision-making in safety, environmental control, and industrial process supervision.

Collaboration sought:
Technical Cooperation Agreements, Joint Ventures, or Commercial Agreements with technical assistance are sought with companies or R&D institutions interested in developing application-specific sensors, integrating the IR gas remote sensing technology into real-world environments, or carrying out joint R&D activities for industrial, environmental, or safety applications.
