The wave front distorted after propagating through the turbulent atmosphere, which causes the decrease of performance in an optical system. At the position of vortex, the amplitude is close to zero. Around the vortex core, the phase can be positive or negative. At this article, an optical vortex of scintillated Airy beam was simulated by Fractional Fourier transform and without Fractional Fourier transform. For simulation of an optical vortex after propagating the distance z, we use the Fresnel diffraction integral. Fractional Fresnel integral can be calculated By the paraxial approach. The positions of an optical vortex Airy beam for Fractional Fourier transform and without Fractional Fourier transform are different. For simulation of scintillated beam, we use the phase screen that expressed by Zernike polynomial. The results show that vortex location changes with different turbulence.

Keywords: optical vortex, phase screen, Airy beam, Fractional Fourier transform
