Abstract.  We studied periodic aperture imaging with various subaperture configurations in terms of their point spread functions, optical transfer functions, and imaging quality. A circular-shaped unit cell provides the best performance compared to square- and cross-shaped unit cells when the total aperture size and collection area are kept the same. Moreover, decreasing the separation among the unit cells or the number of subapertures also improve the imaging performance. Results have potential applications in optical periodic aperture telescopes, diffraction masks, and coded aperture imaging.
