Abstract :
Improving the resolving power of diffraction-limited imaging devices has most often been accomplished with costly increases in the size of the imaging aperture. To minimize cost and construction difficulty yet still improve image resolution we use a dilute aperture imaging system followed by post-processing with the Poisson maximum a-posteriori (PMAP) algorithm to achieve image reconstruction and super-resolution. We give a description of the algorithm as well as show an example of its performance on images taken with a dilute aperture optical system
