Abstract

Microbolometers Focal Plane Arrays (FPA) are uncooled infrared arrays suitable for the detection in the 8-14μm spectral range. Standard products show attractive performances and are available at low cost. They can be consistently used for space missions on microsatellites. A microbolometers focal plane array (a 640x480 microbolometer array with a pitch of 25 μm) is foreseen to be used on the Mistigri mission proposed by CNES (French National Space Agency). The scientific objectives of the mission are the monitoring of water conditions of agricultural crops and natural vegetation. These objectives can be reached thanks to observations in the thermal infrared wavelength. Mistigri is now at an early stage of development (preliminary definition study). CNES has started a technological evaluation on the microbolometers array as a risk mitigation action. This technological evaluation plan includes radiation tests (ionizing dose, displacement damage, and heavy ions), lifetest, thermal cycling and vibrations and shocks. At the same time we have addressed fine performances of the microbolometers arrays in order to optimize instrument design and performances.
