Semi-automatic phase shift calibration using digital speckle pattern interferometry
Optics & Laser Technology, 1995Abstract A semi-automatic method for calibrating phase shifting devices using a simple speckle pattern interferometric arrangement has been demonstrated. The method applies a simple two-beam digital speckle pattern interferometer (DSPI) and a personal computer with a frame grabber to achieve this purpose. The principle of the technique, together with

Random phase measurement errors in digital speckle pattern interferometry
Optics and Lasers in Engineering, 1997Phase measurements using digital speckle pattern interferometry are subject to random errors due to speckle decorrelation and electronic noise. A phasor description of speckle decorrelation is introduced from which the rms phase error is calculated. Phase noise due to additive Gaussian errors on the phase-stepped images is shown to be statistically ...

Structural Integrity in Aging Aircraft, 1995
Abstract Two optical techniques, ESPI (Electronic Speckle Pattern Interferometry) and Digital Speckle Correlation are employed to reveal the existence of crevice corrosion which is usually undetectable from outside by visual inspection. The ESPI is configured to measure out-of-plane displacement.
