| Abstract: | Aiming at the impact of digital speckle pattern interferometry on the transient vibration measurements, the technology on double digital speckle pattern interferometry was conducted. Uniform distribution of laser beam energy by space filter is achieved, and double-pulse laser and high-speed camera work synchronously by controlling time accurately. The transient speckle interference pattern is acquired with the proposed method. The research seeks to investigate and provides transient vibration measurements with double-pulse interval from 2μs to 800μs. |
