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(More)
Interactive simulations have been developed illustrating basic principles of physical optics in three major areas: 1) electric field behavior in various polarization states, 2) propagation of traveling plane waves through birefringent and optically—active media, and 3) Fresnel diffraction and its relationship to and interpretation with Cornu's spiral.
