Hybrid Reflective Interferometric System Combining Wide-Field and Single-Point Phase Measurements
We present a hybrid scan-free reflective interferometric system, which combines a wide-field phase measurement, together with a single-point phase measurement, for optical inspection of thin reflective elements.

Reconstruction of a three-dimensional, transonic rotor flow field from holographic interferogram data [PDF]
Holographic interferometry and computerized aided tomography (CAT) are used to determine the transonic velocity field of a model rotor blade in hover. A pulsed ruby laser recorded 40 interferograms with a 2 ft dia view field near the model rotor blade ...

Adaptive Aperture Defocused Digital Speckle Photography
Speckle photography can be used to monitor deformations of solid surfaces. The measuring characteristics, such as range or lateral resolution depend heavily on the optical recording and illumination set-up.
