摘要: Based on the Collins diffraction formula and by means of expansion a hard aperture function into finite sum complex Gaussian functions, two analytical approaches Finite Olver beams (FOBs) passing through paraxial ABCD optical system with circular annular or rectangular one are developed in this paper. The propagation properties FOBs an unapertured last (or rectangular) black screen deduced, from main results, as particular cases. Also, characteristics ordinary Airy beam all considered systems derived here that correspond to zeroth-order FOBs. According predicted formulas, computer simulation examples given deepen understanding some basis.
