摘要: 用矩阵方法研究了多元件光腔,特别是含透镜腔和望远镜腔的分数傅里叶变换特性,然后从广义惠更斯菲涅耳衍射积分公式出发,推出了光腔的分数傅里叶变换的二维衍射积分表达式和分数傅里叶变换的矩阵表示式,并作了讨论.

Abstract: The characteristics of multielement optical resonators,in particular,the resonator with an internal lens and telescopic resonator which can be represented in terms of fractional Fourier transforms(FRFTs) have been studied by means of the ABCD matrix method.Then,starting from the generalized Huygens-Fresnel diffraction integral,the two-dimensional diffraction integral of optical resonators expressed as FRFTs has been derived and the corresponding matrix formulation has been given and discussed.
