In this paper, we investigate a detailed study of the optical image produced by MQBG beams propagating through a Fractional Fourier Transform system (FFT) with two circular apertures. The approximate analytical formula of the MQBG intensity distribution was derived by using the extended Huygens-Fresnel principle and the expansion of the hard-edged circular aperture function. Some numerical simulations are illustrated to the effects of a FFT optical system on the propagation of MQBG beams. The simulations show that the order of the Fractional Fourier Transform and the beam parameters change the field distribution.
