Patent US 4,029,960

A device for the recording and reproduction of X-ray pictures utilizing a layer of amorphous selenium which is disposed in a housing, the selenium being carried by a thermoplastic layer, preferably having a further dielectric reflective layer interposed between the selenium and the thermoplastic layers, with an electrode being disposed at the other side of the selenium layer on the free surface thereof, at which side the X-ray beam impacts the device. The recorded structure may be read-out by the use of a schlieren or phase-contrast optic which is disposed to receive optical radiation reflected from the recorded structure, with the optical radiation being directed on the structure by a partially transmissive reflector disposed between such recorded structure and said optics, whereby reflected light from the structure may pass through the reflector to said optics, and focused, for example, on a viewing screen.
