ABSTRACT:
A light amplification device utilizes a light intensification tube and optical feedback means 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.
