| Abstract: | The diffraction formula for an arbitrary wave by small aperture is used to calculate the intensity and power distribution for the diffraction pattern of some Gaussian beams by several annular apertures. The errors of the optical quality factor evaluated on the base of the diffraction by circular apertures are evaluated for optical systems with annular apertures. It is concluded that the wave type and aperture geometry have to be taken into account in evaluating the optical quality of an optical system. |
