Video technology is applied to the problem of moiré metrology. In the past, moiré metrology seemed a promising yet limited method in the measurement and comparison of surface shape. The use of video technology has widened the area of application of moiré metrology by reducing the complexity of the optical set up and providing real time information on surface shape and by: 6.

Holographic interferometry (HI) is a technique which enables static and dynamic displacements of objects with optically rough surfaces to be measured to optical interferometric precision (i.e.
to fractions of a wavelength of light). These measurements can be applied to stress, strain and vibration analysis, as well as to non-destructive testing and radiation dosimetry. Interferometry is a powerful tool. It enables measurements of surface topography, dimensional changes and deformations of solid bodies, all in the sub-wavelength sensitivity range.

Sciammarella, C. Sciammarella, C. Sciammarella, L. Lamberti. 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, e.g., 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. Book review Full text access Moiré techniques, holographic interferometry, optical NDT, and applications to fluid mechanics: Chiang, F.

Moiré topography in particular is a widely used means for shape contouring of three-dimensional objects (3D). The technique of the moiré is a process using.
Analysis of Moiré interferometry patterns allows the fiber axial and interfacial shear stresses to be calculated along the entire fiber length. The interfacial shear stress distribution along the debonded length of the fiber indicates a steep decrease in shear stress with interfacial slip, from 6 to 1 MPa for 7 μm of fiber slip and a crack.
Holographic interferometry is the term for all interference phenomenons in which at least one of the waves which creates the interference is produced by a hologram.
Consequently, the most original characteristic of holographic interferometry is to permit interference by two contemporary waves. Holographic Interferometry Aim: Covers the basics of frozen fringe, live fringe and time averaged holography is simple geometries.

Moiré topography is a full-field optical technique in which the shape of object surfaces is measured by means of geometric interference between two identical line gratings.
The technique has found various applications in diverse fields, from biomedical to industrial and scientific applications. The book presents the principles and methods of holographic interferometry - a coherent-optical measurement technique for deformation and stress analysis, for the determination of refractive-index distributions, or applied to non-destructive testing.
Emphasis of the book is on the quantitative computer-aided evaluation of the holographic. a moiré fringe with order of x will appear, where a positive sign means a compressive strain, while a negative sign represents a tensile strain.
However, in order to obtain clear and measurable moiré patterns in the LSCM image, it is a practical necessity that the number of moiré fringes be less than one-half of the number of scan lines, i.e. Optical Flow Sensor Using Geometric Moiré Interferometry We report on a feasibility study of an optical micro-electro-mechanical systems (MEMS) flow sensor to measure flow rate using Moiré fringe displacement of a floating element.

The basic technique involves recording a hologram of the object of interest and then interfering the image produced from this hologram with the coherently illuminated object itself.
A variation on this technique would be to form two. A new method of interferometry, based upon holographic photography, is described.
The interferometer uses a common optical path in which beam separation is achieved by two exposures separated in time. Its significant advantages are (1) accurate alignment and precision optical elements are not required, (2) differential interferometry, used to measure small changes in either optical path or.
