Abstract

A detector for detecting invisible radiation and charged particles is composed of at least one radiation-absorbing panel and at least one optical waveguide arranged parallel to the surface of said panel and containing a fluorescent dyestuff. The luminescent light produced in the panel by the absorbed radiation is converted into a fluorescent radiation in the optical waveguide conducted to a photosensitive semiconductor component by total reflection and measured at that point.
