针对分幅面成像任意反射面速度干涉仪(VISAR)时间分辨和速度分辨的不足，研制了一套超高时间分辨空间相移面成像VISAR。用双VISAR干涉腔光路解决超短脉冲相干性问题，实现超高时间分辨；用沃拉斯顿棱镜代替传统点VISAR中的偏振分束棱镜分光实现简洁的空间相移光路；以梳状干涉条纹作为信号载体实现空间分辨；用空间变换方法实现相移条纹的像素匹配；再由四路推挽式信号处理方法获得相位，进而获得全场速度分布。该套面成像VISAR具有150 ps时间分辨和6 m/s速度分辨。用其测量了激光驱动铝膜飞片的速度场，给出了全场速度分布。实验结果验证了超高时间分辨空间相移面成像VISAR的可行性。

In order to overcome the deficiencies of framing plane imaging velocity interferometer system for any reflector (VISAR),a simultaneous phase-shifting plane imaging VISAR with high temporal resolution is developed. With the double interferometers arrangement, fringes can be produced in VISAR with an ultrashort laser pulse. As a substitute for polarizing beamsplitters, Wollaston prisms are used to produce four spatial phase shift interferograms. Then, geometric correction of interferograms is done using space transformation. At last, a push-pull signal processing method is used to obtain the phase and velocities. Full-field velocity map is provided with a temporal resolution of 150 ps and a velocity sensitivity of 6 m/s. The technique is employed to measure a two-dimensional spatial velocity field of Al foils flyer driven by a pulse laser. These experimental results demonstrate the feasibility of the new imaging VISAR.
