Diffraction of light on an opaque thin strip and a slit is considered, providing simple analytic formulas describing Fresnel diffraction patterns for Gaussian-beam illumination. The presented equations provide a simple way to carry out diffraction simulations. Evolution of the intensity distribution of a scattered wave through a rectilinear strip from the near to far field is also shown.
