Previous reports have demonstrated that it is possible to emulate the imaging function of a single conventional
lens with an NxN array of identical lenslets to provide an N-fold reduction in imaging-system track length. This
approach limits the application to low-resolution imaging. We highlight how using an array of dissimilar lenslets,
with an array width that can be much wider than the detector array, high-resolution super-resolved imaging is
possible. We illustrate this approach with a ray-traced design and optimization of a long-wave infrared system
employing a 3x3 array of free-form lenslets to provide a four-fold reduction in track length compared to a baseline
system. Simulations of image recovery show that recovered image quality is comparable to that of the baseline
system
