About this technology
Overview
NASA's Glenn Research Center has developed non-contact, ultra-bright luminescence-based surface temperature mapping and sensing systems capable of operating in environments with extremely high thermal radiation. This is accomplished through the use of a unique chromium-doped gadolinium aluminate (Cr:GdAlO 3 ) temperature-sensing phosphor. This technology has been proven accurate up to 1300°C - a dramatic increase when compared to current state-of-the-art, which has only been demonstrated up to 600°C. In addition to providing breakthrough temperature measurement capability, this innovation is immune to electromagnetic interference, making it ideal for operation in harsh, high-temperature environments. Furthermore, its unprecedented ultra-bright intensity allows for accurate temperature measurements in the presence of high levels of background radiation.
