ABSTRACT:
An optical system includes a window having a nonspherically curved outer surface and a curved inner surface, and a transmission optical corrector adjacent to the curved inner surface of the window. The transmission optical corrector has a selectively nonuniform passive transmission optical property, such as a spatially varying index of refraction of the transmission optical corrector or a spatially varying diffractive property of the transmission optical corrector. The optical system further has an optical train positioned such that the transmission optical corrector lies between the curved window and the optical train. A sensor is disposed to receive the optical ray passing sequentially through the window, the transmission optical corrector, and the optical train.
