An area detection device for use with X-ray or ultraviolet radiation wherein light from an integrating device is passed through an optical fiber to fall on a phosphor-containing film which is capable of storing a diffraction pattern formed by the transmission of X-rays or ultraviolet radiation through a sample when the diffraction pattern is projected onto the film and also being capable of fluorescing in correspondence to the diffraction pattern. Fluoresced light from the film is directed back along the fiber and into the integrating device and is fed from the integrating device to a photomultiplier which sends a signal from which the diffraction pattern can be detected.
