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10μm。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。An imaging-velocity interferometer system for any reflector（VISAR） has been implemented at the ＂Heaven-I＂ excimer laser system,which is applied to laser-driven shock experiments as a method for equation-of-state（EOS） measurement.It contains three parts： input system,imaging-relay system and interferometer system,and a single longitudinal mode laser with 532 nm wavelength is used as the probe light.The imaging-VISAR performs at spatial resolutions better than 10 μm.In the experiment with a single-step aluminium target,the shock velocity and the free surface velocity could be measured simultaneously.
