Diffraction of quasimonochromatic light beams on multilayer inhomogeneous photopolymer holographic diffraction structures

Holographic Synthesis of Diffraction Free Beams and Dark Hollow Beams

Since its discovery, holographic techniques had been proved to be one of the most powerful tools for controlling the optical field in almost all the optical areas [1,2,3]. Just to mention some ones, these techniques had been used in the design of hybrid lenses to decrease or avoid aberrations, in optical metrology it had been used to analyze the vibration modes in order to detect potential risk...

Bessel beams: diffraction in a new light

Diffraction is a cornerstone of optical physics and has implications for the design of all optical systems. The paper discusses the so-called ‘non-diffracting’ light field, commonly known as the Bessel beam. Approximations to such beams can be experimentally realized using a range of different means. The theoretical foundation of these beams is described and then various experiments that make u...

X-ray diffraction characterization of multilayer semiconductor structures*

The analysis of double-crystal x-ray rocking curves of single-crystal layered structures can give valuable information on layer strains, displacement of atoms from normal lattice sites (which reduces the structure factor), crystallographic misorientations, and crystal defects. Both strains and misorientations cause shifts in the Bragg angle. These two effects are readily separated using two or ...

Limited diffraction array beams

Limited diffraction beams have a large depth of field infinite aperture. Because of their high side lobes and complex and could have many applications. In this article, new limited diffracbeam patterns near the cone surface, these devices are not curtion beams are developed. They are composed of multiple parallel rently used in clinics. Ring antenna [42] or transducer [43,44] is beams and are t...
