Multi-aperture imaging systems can reduce the size, weight, and cost of an imaging system while maintaining resolution. Using anamorphic pupil remapping and computational phase correction algorithm can reduce field dependent contrast and lead to piston corrections for partially coherent illumination. Rotational aperture synthesis can combine piston corrected images and increase resolution in multiple axes.
Multi-aperture imaging systems can be used to decrease the size, weight, and cost of an imaging system while retaining a resolution related to the diameter of the aperture gain. One solution for phasing apertures in an array uses anamorphic pupil remapping and a computational phase correction algorithm. It is shown that using blazed gratings to remap the aperture fields reduces field dependent contrast and leads to piston corrections for partially coherent illumination. Additionally, rotational aperture synthesis is used to combine two piston corrected images and create an image with resolution increases in more than just the axis of aperture gain.
