  In this paper, we discuss the possibility of imaging molecular orbitals from
photoelectron spectra obtained via Laser Induced Electron Diffraction (LIED) in
linear molecules. This is an extension of our work published recently in
Physical Review A \textbf{94}, 023421 (2016) to the case of the HOMO-1 orbital
of the carbon dioxide molecule. We show that such an imaging technique has the
potential to image molecular orbitals at different internuclear distances in a
sub-femtosecond time scale and with a resolution of a fraction of an
Angstr\"om.
