Night Television System.

Abstract

Tests were conducted during a 15-month period from January 1957 to March 1958 to determine the effectiveness of the type 6849 Image Orthicon Camera Tube manufactured by Radio Corporation of America, as a light-sensitive pickup device when used in television camera systems during the hours of darkness. Three lenses were used during the tests: An f/0.87 76mm, an f/1.9 50mm, and an f/3.8 135mm. Preliminary tests under low light level conditions revealed that the f/0.87, 76mm Super-Farron high speed objective lens, manufactured by the Farrand Optical Company, New York City, New York, was the only lens of those tested which yielded useful imagery. Field tests were conducted over the period 10 days before and 10 days after full moon under 'visibility unlimited' conditions. Controlled laboratory tests were conducted using incandescent lamps for illumination.
