摘　　要： 分数傅里叶变换已经引入标量衍射理论,但实际应用方面的研究成果相对较少,特别是用于衍射计算。将分数傅里叶变换直接应用于衍射的模拟,并与传统标量衍射理论进行比较。研究表明,分数傅里叶变换结果可以解释激光光场的传输与变换,可以更广泛地应用于信息光学中。 Fractional Fourier transform has been introduced into scalar diffraction theory. However, research results on the practical applications are relatively insufficient, especially the diffraction calculation. In this paper, Fractional Fourier transform is directly used in the diffraction simulation, compared with that from traditional scalar diffraction theory. The results show that the fractional Fourier transform can explain the transmission and transformation of laser hght field and can be widely used in information optics
