ABSTRACT:
A method of and apparatus for imaging light opaque specimens wherein a secondary source (16) is stimulated by radiation (x-rays or high energy electrons or neutrons) transmitted through the specimen (12) and visible light emitted by the secondary source (without amplification) is detected by a cooled slow scan CCD (26, 28) coupled to the secondary source by a lens (20) and shutter (22).
