<p>A light amplification device utilizes a light intensification tube (11) and optical feedback means (15-16 and 31-36) for feeding back to the intensification tube for further intensification an image already intensified thereby. The feedback means is connected in such a manner that the fed-back image and the image being intensified for the first time are fed into separate, non-overlapping portions of the input surface of the light intensification tube. </p> |
