  • Optimizing the etalon for multiple laser beam penetration.
  • Implementing a four-point bisensitivity configuration.

    • Main Results:

    • The new VISAR system enables accurate measurement of small velocities with a relatively short and inexpensive etalon.
    • The delay time is effectively increased by utilizing different reflection paths within the etalon.
    • A velocity per fringe reduction of approximately three times was achieved for the laser beam with a smaller incident angle.
    • The system demonstrated velocity per fringe capabilities of 100 and 350 m/s with a 200 mm diameter, 150 mm length etalon.
    • Successful measurement of a steel flyer driven by an explosive was conducted.

    Conclusions:

    • The proposed four-point bisensitivity VISAR with a renovative delay etalon offers a significant advancement in dynamic velocity measurement.
    • This technology provides a more sensitive, compact, and cost-effective solution for high-precision velocity measurements.
    • The system is applicable to various scenarios requiring accurate dynamic velocity tracking, such as explosive-driven material experiments.
