Abstract
We suggested the hexagonal aperture to compute the point spread function (PSF) by making use of scalar diffraction theory and Fourier operations. We have got an analytical formula for the PSF corresponding to the hexagonal aperture. We compared the PSF results with that computed by applying the Fast Fourier transform. Hence, we have got the spatial resolution from the cut-off corresponding to the PSF plot using the hexagonal aperture. In addition, we gave an application of hexagonal and circular apertures using the CSLM. Finally, we have got the reconstructed images using the CSLM provided with circular and hexagonal apertures.
