Dynamic electronic speckle pattern interferometry (ESPI) can now be studied in the time domain. This research presents a method to estimate phase in fast ESPI experiments by using short laser pulses, even when temporal sampling is insufficient.

Area of Science:

  • Optical Metrology
  • Experimental Mechanics
  • Digital Imaging

Background:

  • High-speed digital video cameras enable time-domain analysis of electronic speckle pattern interferometry (ESPI).
  • Temporal ESPI requires properly sampled fringe patterns to meet Nyquist criteria for transient phenomena.
  • Fast transient events can exceed the temporal sampling capabilities of current ESPI systems.

Purpose of the Study:

  • To analyze and extend the measuring range of algorithms for phase extraction in dynamic ESPI experiments.
  • To investigate methods for estimating the modulating phase when temporal sampling is insufficient.
  • To adapt ESPI for analyzing transient phenomena that occur too rapidly for conventional temporal sampling.

Main Methods:

  • Utilizing short laser pulses or brief video acquisition windows with significant temporal separation.

  • Estimating the modulating phase of dynamic ESPI experiments under limited temporal sampling.
  • Ensuring adequate spatial domain sampling of the modulating phase for accurate reconstruction.

    • Main Results:

    • A method is presented to estimate the modulating phase in dynamic ESPI experiments with insufficient temporal sampling.
    • The technique leverages short acquisition times and spatial domain sampling to overcome temporal limitations.
    • Successful phase estimation is demonstrated even when the Nyquist criterion for temporal sampling is not met.

    Conclusions:

    • The proposed method effectively extends the capabilities of time-domain ESPI for analyzing fast transient events.
    • Short laser pulses and strategic temporal separations offer a viable solution for phase estimation in challenging ESPI scenarios.
    • This approach enhances the applicability of ESPI in fields requiring the study of rapid dynamic processes.
