We present the defocused differential interference contrast (DIC) imaging of gold nanorods. We found that the scattered light and the defocus aberration play an important role in the formation of orientation-dependent DIC image patterns of a gold nanorod. Interestingly, the scattered light from a gold nanorod aligned closer to the polarization directions enables us to directly resolve its spatial orientation under a defocused DIC microscope.
