Investigation of irregular apertures and applications in confocal microscopy and speckle imaging

I suggest an irregular aperture and calculate the impulse response, or the point spread function (PSF) corresponding to this aperture. In addition, I calculated the PSF in the case of rotated irregular apertures. Secondly, I apply these irregular apertures to the confocal scanning laser microscope (CSLM). I obtained the images using the CSLM provided with irregular apertures and compared them with the case of uniform circular apertures. Finally, I differentiate speckle images that were obtained using different orientations of the irregular aperture. Then, I reconstructed the irregular aperture at different orientations from the speckle pattern.
