Opt. 29, 5262-5267 (1990). doi: 10.1364/AO.29.0052620003-6935http://hdl.handle.net/10919/46891Distortion-free imaging through a system with aberrations is possible for a certain class of input. The input spatial spectrum must be restricted to spatial frequencies which are equally affected by the aberrations (i.e., which experience identical phase shifts mod2-pi). We demonstrate experimentally that if the aberrations can be localized in the pupil plane, an arbitrary input can be prefiltered to produce a distribution which is imaged without distortion by an aberrant system. Equivalently, the output of the system can be postfiltered to select the information which was imaged without distortion.en-USIn CopyrightArticle - Refereedhttp://www.opticsinfobase.org/ao/abstract.cfm?URI=ao-29-35-5262https://doi.org/10.1364/AO.29.005262
