Operational Objective Camera (OOC) Manufacture: ITEK. The OOC was made in the Boston division of ITEK, replaced by the OBC.  ITEK was originally an Italian manufacturer of eyeglasses and frames.  The OOCs were panoramic cameras with a 13 inch focal length using 70 mm wide film.  Both Right and Left had their views fixed with respect to the vertical and scanned horizontally from -5 degrees below the aircraft nadir out to +45 degrees on their respective sides. Both right and left OOC's had their views fixed with respect to the vertical and they scanned horizontally from -5 degrees below the aircraft nadir out to +45 degrees on their respective sides. The cameras were able to set their framing rates so at the current ground speed (from the Nav system) each photo would overlap the area covered by the previous photo by 55%. That is what provided the ability of the PI's to obtain Stereo views from the OOC photos. The OOC's were discontinued in the early 1970's.  

 

The Optical Bar Camera (OBC) could photograph 100,000 square miles of the Earth's surface per hour. Film image 72 miles wide, & film length 10,500ft. Initially a 24 Inch focal length lens; later extended to 30 inch focal length . Both cameras (OBC and TEOC) provided  superb detailed high resolution photographic images horizon to horizon.
