  Any practical imaging system, be it reflection, refraction, or
diffraction-based, is basically band limited and therefore is bound to be
affected by airy pattern noise. Apodization of the passband is most often
applied as a preferred method to get rid of these unwanted artifacts. But it
comes at a cost of losing resolution as higher frequencies are tapered in
apodization. Here, we propose and demonstrate a novel technique for
discriminating the airy lobes based on their phase. We could thus eliminate the
dominant noisy lobes without compromising with the resolution of the imaging
system.
