INVISIBLE LIGHT PUTS U.S. SOLDIER ' ON TARGET ' AT NIGHT . The sniper scope and other infrared ray devices to enable troops to operate in good light invisible to the enemy have been developed at the research and development laboratories, Virginia U.S.A. The sniper scope, used with success against the Japanese late in World War II and since improved, operates by using an incandescent light source with a filter that allows only invisible infra-red rays to be omitted. Reflections from these rays are picked up by special tube which transforms them into actual images. A target can be pinpointed in total darkness at distances of up to 100 yards. The instrument can be hooked onto a rifle or operated independently, and it weighs only 4 pounds. PICTURE SHOWS:- The image ( White Circle ) viewed through the sniperscope , attached to the rifle used by the soldier on left . 6 December 1950.
