| Popis: | International audience; Multispectral imaging is a proven technique for remote sensing applications such as multiband imagery or gas leaks detection. Especially, snapshot multispectral cameras offer a compact solution for measurements at high framerates. In this paper, we present the development of a MWIR multispectral plenoptic camera with a cryogenic multispectral core and a front lens, for remote sensing at long ranges. This solution is based on a sensitive cooled infrared detector commercialized by LYNRED. The Dewar of the detector is a sealed, cryogenic and binding environment originally dedicated to the detector only. Over the past years, ONERA and LYNRED have developed a strong experience in integrating optical components in the Dewar of the cooled detector, in order to increase the compactness of cameras. Thanks to this experience, key optical components such as an array of filters are directly integrated in the Dewar. Experimental results are shown and compared to simulations. |
