Abstract

OCA, under contract to Spar Aerospace, has developed a space-qualified zoom color video camera. The optics are a 9.3:1 f/2 zoom lens under digital servo control, using only two moving groups to accomplish zoom, compensation, and focus over an object distance range from 355 mm to infinity. Accomplishing three functions with two moving groups both improves reliability and allows better aberration correction than conventional zoom lenses using front-element motion to focus for range. The detector is a single chip array with integral color filter array. Important lens features include excellent image quality; performance in a near-earth orbit for 10 years without maintenance; and the development of an algorithm allowing accurate photogrammetric ranging from 355 mm to 10 meters.
