We have investigated the photoelectron spectra from ionization of diatomic molecules by an attosecond XUV pulse in a strong infrared laser field by quantum calculations. A clear holographic interference structure is observed in the two-dimensional photoelectron momentum spectrum. Moreover, this holographic structure depends sensitively on the electron orbitals and internuclear distance of diatomic molecules. Based on the orbital dependence of the holographic structure, one can identify the symmetries and electron density distributions of molecular orbitals. This indicates that the photoelectron holography by an attosecond XUV pulse in a strong infrared field can be used as an efficient tool for molecular imaging.
