    Abstract

    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.
