Light receiving and detection system for reading a radiographic image

An apparatus and a method for receiving and detecting light from a plurality of light scanning operations on each scan line of a document, such as a radiographic image, which is being read. The light is detected by means of a photo-diode detector arrangement. Prior to detection, however, this light is received in an integrating arrangement. In effect, a progressive point of light from each optical fiber used for delivering of the light occurs from one end of a scan line to the other sequentially, from scan operation to scan operation. When the light emits from each of a plurality of optical fibers, the light then spreads somewhat into a cone. A reconcentrating and refocusing lens, such as a Selfoc lens, refocuses the spreading light into a point in the image plane of the radiographic film being scanned and essentially refocuses that light at that image plane. Detection of the light is made on a clock time basis so that the light content at each scan operation in a scan line so that recreation of the document is readily made.
