        Laser driven inertial confinement fusion ( ICF ) is an important platform for high-energy-density physics research under extrame conditions . In ICF research , high-quality shock waves are key to fusion energy release. The Velocity interferometer system for any reflector ( VISAR ) is an active shock wave velocity measurement technique , which is the most important diagnostic technique for measuring quantities such as shock wave and particle velocities . It is capable of capturing the evolution of shockwave velocity along a line and has important applications in field such as the study of material high-pressure properties and inertial confinement fusion research .
        In experiments , due to factors such as non-uniform loading from the driver and inhomogeneities within the ablator material , the shock wave velocity field often exhibits two-dimensional spatial inhomogeneities. So, to meet the increasing demands of ICF experiments, we have developed a diverse range of speed measurement technologies. Including Line VISAR , Dual-axis VISAR , 2D-VISAR , and Compressed Ultrafast Photography ( CUP )-VISAR. Each configuration is custom-designed to meet specific experimental needs and challenges in ICF.
