ABSTRACT:
A phosphor screen constructed by forming a phosphor layer on one side of an optical fiber plate consisting of a large number of bundled single optical fibers, each of which fibers comprises a cylindrical core and a clad surrounding the curved surface of the fiber core. At least that side of the respective fiber cores which faces the phosphor layer is removed, to provide a depression. Sufficiently large spaces are formed between the fiber cores and phosphor layer, to prevent both members from being brought into optical contact with each other.
