An optical system has been developed which is used to document inertial fusion experiments. It records both classical interferograms of solid hydrogen isotope layers within the hollow spherical fuel container prior to the shot and holographic interferograms of the plasma during the implosion. This optical system has the advantages of visible and UV utility, 2--4 ..mu..m resolution and a low space requirement. Both systems share a catadioptric objective lens and a refractive relay lens. The visible classical interferometric beam and the UV pulsed holographic probe follow different off-axis paths within the object cone of the lenses. To document the solid layer, the beam is diverted to a shearing cube interferometer using a lens-mirror assembly on a sliding stage. This assembly then slides out of the way which records four holographic interferograms of the plasma separated in time by 40--400 ps. The two operation modes, shearing interferometer and holographic, are serial; switching from one to the other requires only seconds.
