Abstract
A method and apparatus for phasing the apertures of a multiple-aperture imaging system is disclosed. An imaging system gathers light in either a scanning or a staring mode from a natural or real scene without artificial light sources. The spatial frequency of the image is sensed. The phase of the apertures is adjusted until the spectral power is maximized within a preselected spatial frequency band. When the spectral power is maximized, the apertures are optimally phased.
