ESA Wide Field Aurora Imager

The monitoring of Aurora from the poles helps preventing from geomagnetic storms which could create dramatic consequence on earth, such as giant black-outs. The ESA space Weather department is ordering a study on a Wide Field Aurora Imager (WFAI) dedicated to the monitoring of Aurora from low-orbiting nano-satellites embarking VIS and  UV wide field cameras. We are in charge of the optical design and prototyping of the UV camera covering a 60x60deg² field of view at 135nm wavelength.

CASTLE, a GW optical chaser

The Calar Alto Schmidt-Lemaître Telescope will use the new technology of curved detectors to address two cutting-edge astrophysical topics, such as the search for the electromagnetic counterpart of gravitational waves and the observation of ultra-low surface brightness objects. This telescope will be located at the Calar Alto Observatory and it will also be used as an educational tool for secondary schools. Part of the observing time, ~20% will be opened to the community. The full project will be carried out in collaboration with a team at IAA-CSIC (Institute of Astrophysics of Andalusia in the Spanish National Research Council) where I will be located.

CURVE One S.A.S.

CURVE-One develops the technology of curved/freeform imaging detectors and provides solutions for compact and cost-effective cameras and optical systems.

Founded in 2019, CURVE One counts four employees, all working together for more than 5 years.  Our close-knit team gathers the following technical skills: Curved/freeform detectors manufacturing, testing and characterization.  Optical design of compact/high performance cameras with freeform detectors.

As for today, we are supported by two European Commission Horizon-2020 programs, an ERC Proof of Concept Grant and an ATTRACT project. We develop a scientific camera for the Institute of Neurosciences in Marseille and we work with the European Space Agency (ESA) for the design and prototyping of a compact space UV camera for Aurora monitoring.
