Ensquared power for obscured circular pupils with off-center imaging.
Power incident upon square detectors in the focal plane of diffraction-limited optical systems with obscured circular pupils is computed as a function of the line-of-sight position on the detector. The results are applied to an analysis of the dependence of the signal-to-noise ratio on detector size for obscuration ratios of 0, 0.25, and 0.5 and for line-of-sight position on the detector.
