Optical System Design of Imaging Velocity Interferometer System for Any Reflector
Imaging velocity interferometer system for any reflector (VISAR) is an important diagnostic tool for various experiments involving laser-driven shock-wave propagation. On the basis of the imaging VISAR implemented at the Shenguang-Ⅲ prototype laser facility, a novel imaging VISAR system with a magnification ratio of 30 is proposed. Making use of the imaging VISAR, velocity of free surface and shock-wave traveling through transparent media can be measured. The main improvement is made due to the disadvantage of the former system. Details of the optical designing are also described. The design results show that the spatial resolution is better than 5 μm, and the whole system is more effective than the former.
