Related to Interference pattern: Diffraction pattern


In the law of Patents, the presence of two pending applications, or an existing patent and a pending application that encompass an identical invention or discovery.

When interference exists, the Patent and Trademark Office conducts an investigation to ascertain the priority of invention between the conflicting applications, or the application and the patent. A patent is customarily granted to the earlier invention.

Qualitative visual analysis of MUPs and interference patterns may be useful for diagnosis when there are clear changes, but this approach maybe misleading in patients with more subtle lesions [1].
Therefore, a charged object cannot lead to a measurable shifting of the interference pattern. The scalar field of 5D gravity due to the Earth can neither vary the interference pattern, because it evenly affects both the beams of laser light.
The original shape is successfully reconstructed in the interference patterns, but the boundaries parallel to the x-axis are obscure compared with those parallel to the y-axis.
Unlike existing mainstream embossed holograms, which record images in physical relief on the surface of the material, the newly developed hologram is a Lippmann hologram, which stores images by recording interference patterns in photo-sensitive layers produced by laser.
and the interference pattern spreads and is part of the whole of each of the previous patterns" (p.
We notice a phase shift of the interference pattern by arg <[[psi]'.sub.ref]|[[psi]'.sub.f]>.
A correlation algorithm finds the coherence peak position of an interference pattern produced by selectable bandwidth light sources, providing high resolution and sensitivity to returning light.
The differences in the height of specimen structures are then determined by measuring the phase shift in the interference pattern. This technique effectively allows the measurements of step heights on the order of 20 nm to 5 microns with a high degree of accuracy and repeatability, according to the company.
It uses a patented algorithm to find the coherence peak position of an interference pattern produced by a selectable bandwidth light source.
A conclusion, which comes from the contradictions between these experiment results and the existing knowledge in modern anatomy, histology, neurology, and biochemistry, is that there is an invisible dissipative structure the electromagnetic field, which is mainly composed of an interference pattern of standing waves in the resonance cavity of human body under the condition of permanent support of energy in an open system.
The beams are steered at each other, thus creating an interference pattern, explained Bevan.
