Reflective coating for solid-state scintillator bar.

摘要

A multilayer film for coating an exterior of a scintillation detector bar (40) includes a pressure sensitive adherent layer (56) containing a percentage of a light-diffusing material therein for affixing to an external surface of the bar. A clear plastic layer (58) separates the adherent layer from a specularly reflecting layer (60). A protective layer (62) is disposed atop the specularly reflecting layer. The light-diffusing material and the specularly reflecting layer cooperate to retain light within the bar, direct light in random directions within the bar and block optical crosstalk between adjacent bars. A preform consisting of a single piece of film may be used for covering five sides of the bar.
