Recent developments of infrared array cameras in France

We describe three recent infrared cameras, developed in France and based on mosaïcs of infrared detectors. They are optimized for ground-based observations in the 1–5 m or 5–17 m ranges. The results already obtained, emphasize the interest of studying the sky in that domain.Paper presented at the 11th European Regional Astronomical Meetings of the IAU on New Windows to the Universe, held 3–8 July, 1989, Tenerife, Canary Islands, Spain.
