Abstract
An improved thermal radiator uses host materials having high internal reflection and scattering co-efficients for improved effectiveness. Selective thermal radiators are used for frequency conversion of incident radiation through the Welsbach effect. A Welsbach material screen is used to convert incident IR radiation into visible radiation, permitting visual observation of IR radiation and facilitating control and monitoring of IR equipment. Welsbach material is also used as a dynamic IR target which converts incident visible radiation into a high resolution IR source pattern. Welsbach material is also employed as a temperature stable material for converting solar radiation into heat.
