Surface temperature imaging below 300 K using La(2)O(2)S:Eu

Surface temperature images obtained by the ratioing of visible (5)D(2) and (5)D(1), emissions from a La(2)O(2)S:Eu phosphor coating are demonstrated. The visible phosphor emissions permit imaging with standard CCD cameras. Temperature resolution to 1 K is achieved over a temperature range of 193-293...
