ABSTRACT: The formalism of generalized diffraction integral for
paraxial misaligned optical systems is used to investigate the propagation of
the Modified Bessel-Gaussian (MBG) beam through a misaligned thin lens. The properties
of the propagation of MBG beam traveling through this misaligned ABCD optical
system are discussed. A special case of misaligned circular thin lens is
illustrated analytically and numerically. The shape of the MBG beam at the exit
of the misaligned optical system is unchanged; however the center of the beam
is shifted from the propagation axis in correlated manner with the design
parameters of the optical system.
