Abstract
A radiation sensitive area detection device is disclosed which comprises a phosphor-containing film capable of receiving and storing an image formed by a pattern of incoming X-rays, UV, or other radiation falling on the film and capable of fluorescing in response to stimulation by a light source in a manner directly proportional to the stored radiation pattern; a light source capable of projecting light or other appropriate electromagnetic wave on the film so as to cause it to fluoresce; means, such as a lens, to focus the fluoresced light coming from the phosphor-containing film after light stimulation; and at least one charged coupled detector or other detecting element capable of receiving and digitizing the pattern of fluoresced light coming from the phosphor-containing film. The device of the present invention will be able to generate superior X-ray images of high resolution from a crystal or other sample, and will be particularly advantageous in that instantaneous near real time images of rapidly deteriorating samples can be obtained. Further, the device can be made compact and sturdy, thus capable of carrying out X-ray or other radiation imaging under a variety of conditions…
