A Study of the effect of the circular aperture radius on the diffraction light intensity along the optical axis and along the geometric shadow boundary through its relationship to Rayleigh distance

Abstract

In this research, we focused on the light intensity resulting from the diffraction of light through a circular aperture along the optical axis, as well as the intensity along the geometric shadow boundary. In addition, we studied the effect of the circular aperture radius on the diffraction shape through its relationship with the Rayleigh distance in terms of the wavelength of light used, for the following two cases: the intensity along the optical axis, and the intensity along the geometric shadow boundary.
