WebAn optical sensor system having an extended elevation field of view and in which the optics are configured around an all-reflective four-mirror reimaging anastigmat used for afocal … Webhalf angle mirror (HAM), that rotates at half the speed of the RTA, derotating the light beam and directing it into the fixed aft-optics. The path then passes through a fold mirror and a four-mirror anastigmat as it enters the aft-optics. The visible and near infrared light is then reflected by a dichroic beam-splitter onto a focal plane array ...
