Recently the emergence of a new generation of infrared sensors particularly suited to operate at ambient temperature - the microbolometer technology - has opened the opportunity for achieving low cost infrared imaging Systems for both military and commercial applications. In a first part, this paper gives an overview of this challenging technology developed at LETI. A special highlight is given on recent results obtained from a 160x120 focal plane array, 35micron pixel pitch, developed for Driver Vision Enhancement. In a second part, the use of this technology in automotive safety field is illustrated through an application of detection of moving objects in front of a vehicle. The results shows that infrared sensors based on well-designed microbolometers represent a real middle-term alternative to usual video sensors.
