Abstract
The main resolution limit for an electro-optical imaging system comprising a focal plane array (FPA) sensor obeys Nyquist theorem which states that an object must be sampled at more than twice the cut-off frequency to avoid aliasing. A novel super-resolution technique, microzooming (MZ), is presented. MZ provides electro-optical imagery with an extended unaliased bandwidth using multiple aliased images at different optical magnifications. A number of simulation and experiment results demonstrate that MZ is a practical advance for reducing aliasing and enhancing resolution as well as helping to suppress white noise.
