Jianqiang Zhu. A single shot multi-wavelength phase retrieval method is proposed by combining common coherent modulation imaging (CMI) and a low rank mixed-state algorithm together. A new technique for modifying the coherence of a light field is described theoretically, and experimental confirmation is presented.

Holographic interferometry (HI), which provides interferometric comparison of real objects or events separated in time and space, is a technique of unparalleled applications. Various kinds of HI have been developed, . real-time, double-exposure, and time-averaged HI. Furthermore, HI can be performed with one, two, or more reference waves, which can be of the same or different wavelengths.

Some new methods in real-time holographic interferometry are presented in this paper, such as how to. .These techniques are helpful for holographers to improve the precision and efficiency in real-time holographic interferometry.

Some new methods in real-time holographic interferometry are presented in this paper, such as how to obtain a high contrast of interference fringes in real-time holographic interferometry at the stage of recording or reconstruction; how to predict the deformation direction of an object by a simple and reliable method etc. Download PDF.

Holographic and speckle interferometry are optical techniques which use lasers to make non-contracting field view measurements at a sensitivity of the wavelength of light on optically rough (. non-mirrored) surfaces. They may be used to measure static or dynamic displacements, the shape of objects, and refractive index variations of transparent media. As such, these techniques have been applied to the solution of a wide range of problems in strain and vibrational analysis, non-destructive testing (NDT), component inspection and design analysis and fluid flow visualisation.
