1. A method of using an imaging system comprising a focal plane with one or more detectors, a lens optically coupled to the focal plane, a transparent plate optically coupled to the focal plane and lens, the transparent plate being disposed between the focal plane and the lens, and an actuator coupled to the transparent plate, the actuator being configured to move the transparent plate in one or more directions relative to the focal plane, the method comprising:
receiving, at a first area of the focal plane through the lens, light from an object at a first time, wherein the imaging system is located in a first position relative to the object at the first time;
causing the actuator to move the transparent plate in response to movement of the imaging system relative to the object; and
receiving, at the first area of the focal plane through the lens, light from the object at a second time, wherein the imaging system is located in a second position relative to the object at the second time.
