Imaging-velocity interferometer system for any reflector for shock diagnostics
速度干涉仪 空间分辨 单台阶靶 冲击波 velocity interferometer system for any reflector ( spatial resolutions single-step target shockwave
摘要
为了诊断测量激光驱动冲击波，研制了具有空间分辨力的成像型速度干涉仪。该干涉仪主要包括输入部分、像传递部分及干涉部分，探测光采用波长为532 nm的单纵模激光。 在靶位放置一分线板，经过测量，其空间分辨力小于10 μm。基于天光KrF准分子激光系统的参数，设计并自制含有烧蚀层的单台阶金属靶，利用成像型速度干涉仪测量到了金属铝靶内的冲击波速度。
Abstract
An imaging-VISAR has been implemented at the HEAVEN excimer laser system. It is applied to laser-driven shock experiments as a method for equation of state(EOS) measurement. A single longitudinal mode laser with 532nm wavelength was used as probe light. This instrument contains three parts: input system, imaging-relay system and interferometer system. The optical system performs at spatial resolutions less than 10 μm. By using single-step aluminium target, the shock velocity and the free surface velocity could be measured simultaneously.
