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
