摘要：The invention relates to an airborne reconnaissance system which comprises: (a)optical unit for acquiring light rays from a terrain portion, said optical unit comprises a

plurality of optical components that are positioned along an optical path and designedto maneuver said light rays to produce at a focal plane an acquired image of a terrainportion, said acquired image having an area S which is several times larger than the area Aof a focal plane array which is positioned at same focal plane; (b) gimbals unit forperforming a continuous back and forth across-track scanning movement of a respectiveline of sight formed between said optical unit and the terrain below the aircraft; (c) a firstback-scanning mirror along said optical path, for compensating for said continuous acrosstrack movement of the line of sight, said compensation is performed during a respectiveintegration period for a section of said acquired image of area S which falls during saidperiod on said focal plane array; and (d) a second, along-track mirror also positionedalong said optical path, which alternates between plurality of along track states, eachstate causes a different diversion of the light rays within said optical path thereby toimpinge on said focal plane array another along-track section of said acquired image ofarea S; and (e) capturing means for recording in each state of said along-track mirror thecorresponding section of the terrain image which is impinged during said state on thefocal plane array.
