摘要: 运用有序算符内的积分方法推导出坐标-动量表象互换的幺正算符,并给出它在分数傅里叶变换中的应用.

关键词: 幺正算符, 分数傅里叶变换, 坐标-动量表象

Abstract: By using the integration within ordered product of operators,we derive the unitary operator for generating the mutual transformation between coordinate and momentum representation,then we apply it to the fractional Fourier transform.

Key words: unitary operator, fractional Fourier transform, coordinate and momentum representation
