摘要：

Starting from the propagation law of partially coherent light, the spectrum of twisted Gaussian Schell-model (TGSM) beams passing through an aperture is studied. Detailed numerical calculation results are presented, and illustrated. It is shown that the spectral shifts and switches can also take place for TGSM beams, and as compared with the aberration-free Gaussian Schell-model (GSM) beams case, the twist factor affects the spectral shifts and spectral switches. Numerical calculation results are given to illustrate how the twist factor affects the spectral behavior. (C) 2007 Elsevier B.V. All rights reserved.
