Abstract
This paper describes the super resolution technique which is based on the Torlado di Francia imaging technique. The super resolution has been achieved using two masks: phase and amplitude, separately in the same setup. In one case the Mach Zehnder interferometer was used to synthesize the π shifted phase mask while in the second case the negative of amplitude mask was produced. The interferometric multiplication of the original aperture with the synthesized amplitude and phase masks separately gives super resolution in both cases. The achieved Rayleigh resolution is 85% of the conventional system. The side lobes reduction was also obtained in this technique.
