Abstract

Olivier Ouellette and his collaborators have developed a quick, sensitive and cost-effective ultraviolet (UV) radiation detector. Made from microcrystals of a particular mineral, the device constitutes an interesting alternative to current technologies and provides a range of potential applications. First, it detects flames, which have their own UV signature, in real time. This capability could eventually be used to enhance fire tracking and missile recognition—a major technological challenge in the defence sector. Atmospheric science could also benefit from the detector since, for example, the intensity of the UV rays that reach the ground is linked to ozone layer depletion.
