摘要: An imaging system includes an optical system for projecting an object onto a detector, and a phase element between an entrance pupil of the optical system and the detector, the phase element adapted to provide a more uniform modulation transfer function over a range of focus than the optical system alone, wherein an effective focal length of light output from the phase element is a function of an angular component on which the light is incident on the phase element.
