Description du projet
Développement de capteurs d’imagerie infrarouge innovants
Les microbolomètres représentent une solution compacte, légère, à faible consommation, fiable et abordable pour l’imagerie infrarouge. Cela dit, ils accusent un retard de performances par rapport aux capteurs infrarouges refroidis et ils ne sont actuellement pas disponibles pour des applications dans les domaines de la thermographie absolue et de l’imagerie optique des gaz. Le projet BRIGHTER, financé par l’UE, améliorera les performances des microbolomètres en ayant recours à une technologie des pixels innovante, à des circuits intégrés de lecture, à une électronique de traitement du signal d’image à faible consommation et à des algorithmes de traitement d’image. L’introduction de nouveaux capteurs contribuera aux économies de matériaux et d’énergie dans le secteur manufacturier, au développement de capteurs destinés aux véhicules autonomes et à un meilleur contrôle des émissions de gaz dans les villes et les zones industrielles.
Objectif
Micro-bolometer sensors are compact, light, low power, reliable and affordable infrared imaging components. They are ahead of the cooled infrared sensors for these criteria but lag behind them in terms of performance:
- Existing micro-bolometer technologies have thermal time constants around 10 msec. This is more than 10 times that of cooled detectors.
- Moreover, there is no multispectral micro-bolometer sensor available today for applications such as absolute thermography and optical gas imaging.
BRIGHTER will develop 2 new classes of micro-bolometer solutions to reduce the performance gap with their cooled counterparts:
- Fast thermal micro-bolometer imaging solutions with time constant in the 2.5 to 5 msec range, that is to say 2 to 4 times faster than that of today’s micro-bolometer technologies. Read out integrated circuits able to operate up to 500 frames per seconds will also be investigated.
- Multi-spectral micro-bolometer solutions with at least access at the pixel level to 2 different wavelengths in the range 7 to 12 µm.
The developments will focus on pixel technology, Read Out Integrated Circuit, low power edge image signal processing electronic, optics, and image treatment algorithms. All stakeholders of the value chain are involved: academics, RTO, micro-bolometer manufacturer, algorithm developers, camera integrators and end users. They will collaborate to define the best trade-offs for all use-cases.
The 2 new classes of products that will spring from BRIGHTER will generate concrete benefits. They will make it possible to save on material and energy in the manufacturing sector, perform efficient and affordable monitoring of infrastructures and trains, contribute to autonomous vehicles sensor suite, decrease the road casualties among Vulnerable Road Users, better control gas emission in cities and industrial areas. These new usages served by the European industry will allow Europe to increase its market share in the infrared imaging industry.
