Subfeature speckle interferometry

Optics Letters, 1995
A novel speckle technique, subfeature speckle interferometry, is introduced that relies on the amplitude interference of two independent speckle patterns, originating from coherent illumination, by use of an optical system that produces interferometric quality interference fringes on a scale comparable with the speckle correlation length.

Contouring by speckle interferometry

Optics Letters, 1985
An optical method of generating high-constrast contours by using speckle interferometry has been proposed. To demonstrate the use of this technique the conventional dual-index immersion method has been adopted.

Stellar speckle interferometry

Physics Bulletin, 1975
Stellar speckle interferometry is a technique for obtaining diffraction-limited resolution of stellar objects despite the presence of the turbulent atmosphere which limits the resolution of conventional long-exposure pictures to approximately one arc second.

Hololens in speckle and speckle shear interferometry

Applied Optics, 1985
This paper presents a number of methods to obtain in-plane displacement, out of plane displacement and slope data using holographic optical elements. The results obtained with a hololens and a holoshear lens are as good as those obtained with conventional optical systems.
