We have devised a new technique for performing subpixel dithering by using a charge coupled device’s (CCD’s) electronics. By permuting the CCD phases used for collection during the integration mode of consecutive images obtained at a single pointing, one may sample an observed scene at the CCD’s phase spacing rather than at its pixel spacing thus obtaining a factor of three improvement in spatial resolution for a three‐phase CCD, the most commonly deployed format in astronomy. This technique reduces the need for repointing the telescope or instrument, improving operational efficiency, and may be performed with existing multi‐phase CCD architectures. We report on the results of an experimental feasibility study that has quantitatively verified the concept.
