Abstract
An imaging system includes a body, a stage coupled to the body, and a focal plane array including one or more detectors and coupled to the stage. The imaging system also includes a lens assembly including an objective lens and a rear lens group. The lens assembly is coupled to the body and optically coupled to the focal plane. The imaging system further includes a transparent plate coupled to the body and optically coupled to the objective lens and the focal plane array. The transparent plate is disposed between the objective lens and the focal plane array. Additionally, the imaging system includes an actuator coupled to the transparent plate and configured to rotate the transparent plate relative to an optical axis of the imaging system.
