ABSTRACT:
A fiber optic phosphor screen is made of an optical fiber bundle having individual fibers arranged in parallel with opposite ends thereof extending between internal and external surfaces of the screen. The ends of the individual fibers at the internal surface of the screen have phosphor islands bonded only to the core portions in order to provide a pseudo-intagliated phosphor layer. A reflective layer is coated over the phosphor islands in between on the cladding portions of the fibers. A method for producing the fiber optic phosphor screen includes the steps of applying a phosphor-photoresist layer to the ends of the fibers at the internal surface of the screen, illuminating the opposite ends of the fibers such that only the portions of the phosphor-photoresist layer on the core portions of the fibers are developed and bonded thereto, and removing the undeveloped portions of the phosphor-photoresist layer to leave behind phosphor islands bonded to the core portions.
