Optimum performance of a laser-driven cryogenic target requires spherical symmetry and uniformity of the deuterium-tritium (DT) condensate on the interior surface of the fuel capsule. These characteristics are determined, in general, by interferometry. We have developed a shearing interferometer that is free from spherical and chromatic aberration. The detailed structure of the inteferometer is elucidated, and interferograms with a constant phase background and a tilted fringe background are presented.
