Abstract

Optical properties of wide-angle velocity interferometer system for any reflector (VISAR) are studied in this paper. The principle of wide-angle VISAR is expounded. It reveals that the role of the ellipsoid in wide-angle VISAR is to make the inner surface of capsule into a curved virtual image at the center of target. The effect of imaging bending on the formation of dynamic interference fringes is simulated by Zemax and a shaped optical fiber plate is proposed for image correction. The influence of assembly error is also studied. To obtain a good imaging result, the positional deviation of the ellipsoidal mirror should not exceed 30 μm, the inclination should not exceed 4°, the manufacturing error requires less than 0.1 μm in long axis direction and 4 μm in short axis direction, and reflectance needs to be higher than 70%. More possible factors of affecting dynamic fringes, other methods of imaging correction, correspondence between object and image are discussed, along with the potential development of wide-angle VISAR. The optical properties of wide-angle VISAR is a basis for improving the wide-angle diagnostic capability, and is of great significance for the quantitative observation for driving symmetry of capsule in inertial confinement fusion.
