Abstract
In phase imagery it is convenient to block out the uniform background in which a phase structure is immersed. This technique is called dark ground imagery, and it is usually implemented in an approximate fashion by placing in the exit pupil plane either a central obscuration or a phase disk with delay of 180°.
