| Abstract: | By using the normal ordering form of the coordinate,momentum completeness,we directly and concisely introduce the Wigner operator and then illustrate its relation with the Weyl correspondence.The coherent state representation of the Wigner operator is also neatly derived. |

| Keywords: | integration within an ordered product(IWOP) Wigner operator Wigner function Weyl correspondence |
