The deformation, visualised through the interference fringes
, of a large milling machine is an example of Abramson's industrial holographic measurements, shown below.
The rear-surface reflected light from the transparent first reflector is combined with front-surface reflected light from the second reflector to form interference fringes
Testing was a simple matter of placing his convex surface inside the concave reference surface and looking for interference fringes
under monochromatic light.
After applying the proposed method, the interference fringes
of holograms were purified and enhanced.
The refractive index of coherent light is different in different media because of which the optical path difference varies, leading to the movement of interference fringes
This ~1 mm thick glass creates interference fringes
on the FDML light (see Figure 3).
Quantitative estimation of the deformation of the contact surface was carried out by monitoring the deflection of the interference fringes
of the so-called zero-order band.
(2007) Quantum interference fringes
beating the diffraction limit.
The fine scale tracks a domain of typically 16 interference fringes
with a spatial resolution typically 1/16 of a fringe.
If a passport is fixed correctly, the interference fringes
must be parallel to the fixing frame (Figs.
Balanced detector output signal show the interference fringes
