Fresnel diffraction from the edge of a transparent plate with arbitrary orientation of its surfaces is formulated in transmission mode. It is shown theoretically and evaluated experimentally that the thickness of a plate and the angles between its surfaces, near the edge, can be determined accurately. This allows us to construct a quantitative 3D image of the plate edge. It is also illustrated that the recorded diffraction pattern of a plate edge can be regarded as a hologram produced by the interference of two diffracted waves: one passing above the plate and the other transmitting through the plate near the edge. Thus, the hologram makes it possible to reconstruct the plate's edge as a 3D image, and the approach can be utilized in constructing 3D images of phase objects and in quantitative phase microscopy.

Method of using a polycrystalline powder and Rietveld refinement (LEAST SQUARES ANALYSIS) of X-RAY DIFFRACTION or NEUTRON DIFFRACTION. It circumvents the difficulties of producing single large crystals.
The scattering of NEUTRONS by matter, especially crystals, with accompanying variation in intensity due to interference effects. It is useful in CRYSTALLOGRAPHY and POWDER DIFFRACTION.
The scattering of x-rays by matter, especially crystals, with accompanying variation in intensity due to interference effects. Analysis of the crystal structure of materials is performed by passing x-rays through them and registering the diffraction image of the rays (CRYSTALLOGRAPHY, X-RAY).

The region in the dorsal ECTODERM of a chordate embryo that gives rise to the future CENTRAL NERVOUS SYSTEM. Tissue in the neural plate is called the neuroectoderm, often used as a synonym of neural plate.
A type of MONOTERPENES, derived from geraniol. They have the general form of cyclopentanopyran, but in some cases, one of the rings is broken as in the case of secoiridoid. They are different from the similarly named iridals (TRITERPENES).
