The design and description of the optical system for installation in the KC-135 airborne laboratory of AFCRL are presented. The optical system consists of a 4-barrel photometer mounted co-axially with a 16 mm, narrow field-of-view camera as well as 35 mm and 16 mm all-sky cameras. The 4-barrel photometer is capable of either fast-time high-level response for use against artificially induced auroras or by use of the chopper and synchronous detection to monitor the very low-level night airglow radiations. The tilting filter technique is employed on the photometer to monitor the continuum contribution to the line and band intensities to be measured. An automatic calibration system using phosphors excited by C14 radioisotope decay is incorporated. The photometer uses interference filters centered at 4278 A, 4861 A, 5577 A and 6300 A. Author
