Abstract
A prismatic anamorphic system for use with an optical correlator. The prismatic anamorphic system incorporates four rotatable prisms arranged within the optical correlator thereby permitting correlator operation about unity magnification with no image rotation and no axial translation as the magnification is varied. In this manner proper correlation of a pair of photographs can be performed in an economical and highly reliable fashion.
Claims11
A prismatic anamorphic system comprising a base plate having a surface thereon, said base plate having a longitudinal channel therein, a plurality of prisms, said plurality of prisms being arranged along the longitudinal axis of said base plate with adjacent pairs of prisms having their respective bases located on opposite sides of said longitudinal channel, each of said prisms being pivotally connected to said base plate about an axis, the pivotal axis of each of said prisms being perpendicular to said surface of said base plate, means located within said channel for rotating said prisms about said pivotal connections and means operatively connected to said means for rotating said prisms for providing operative power thereto.
