It is in the gamma-ray band, the shortest wavelength part of the electromagnetic spectrum, where diffraction limitations are least constraining, that one might hope for the highest angular resolution. The intrinsic limitations of the imaging techniques used in gamma-ray astronomy are reviewed and the feasibility of obtaining diffraction-limited angular resolution in this band discussed. It is argued that by accepting the necessity of extremely long focal lengths, sub micro arc second resolution along with enormously improved sensitivity should be achievable using diffractive lenses.
