Abstract

The generalized Huygens–Fresnel diffraction integral for misaligned

asymmetric first-order optical systems is derived by using the canonical

operator method, which enables us to study propagation properties of

anisotropic Gaussian Schell-model (AGSM) beams through misaligned asymmetric

first-order optical systems. It is shown that under the action of misaligned

asymmetric first-order optical systems AGSM beams do not preserve the closed

property. Therefore generalized partially coherent anisotropic Gaussian

Schell-model beams called decentered anisotropic Gaussian Schell-model

(DAGSM) beams are introduced, and AGSM beams can be regarded as a special

case of DAGSM beams.
