High harmonics produced in aligned molecules contain structural information on bound electronic states. We have produced high harmonics from N2 molecules aligned in five directions relative to the laser polarization axis. The projected images of the highest molecular orbital (HOMO) are successfully reconstructed based on computed tomography using the observed harmonic spectra. The reconstructed wavefunction includes both amplitude and phase. We also show that attosecond bound-state electron wavepacket dynamics will manifest itself in the high-harmonic spectra.
