Low coherence of the illumination substantially improves the quality of holographic and quantitative phase imaging (QPI) by elimination of the coherence noise and various artefacts and by improving the lateral resolution compared to the coherent holo

This paper summarizes result of research on the cyanobacterial S-layers obtained between 1989 and 1995. In 12 chroococcal strains (of six species) and in one filamentous strain, S-layers were found by electron microscopy and characterized. Laser diff

The symmetry relations of crystal shape amplitudes of the Platonic polyhedra are studied in detail. The general algebraic method for calculating the crystal shape amplitude of any polyhedron is explained. The crystal shape amplitudes of the tetrahedr

The symmetry relations of crystal shape amplitudes of the regular pentagonal dodecahedron and the icosahedron are studied. Graphs of the central cross-sections of the crystal shape amplitudes of these noncrystallographic polyhedra are calculated alon

Some factors that affect the surface measurement accuracy of a low-coherence interference microscope
Publikováno v:
SPIE Proceedings.
Low-coherence interference microscopy (LCIM) is a powerful imaging high-accuracy technique for surface inspection and profiling. The principle of this technique is based on the interference of two waves with the use of incoherent light, usually of ha

S-layers are surface layers of bacterial cell walls. They are formed by two-dimensional, monomolecular crystalline arrays of identical units of protein or glycoprotein macromolecules (subunits). In general, each S-layer exhibits one of four possible

Cyanobacteria are among the most ancient residents of the Earth and were the first oxygenic organisms to provide oxygen to the Earth’s atmosphere by photosynthesis. Cyanobacteria appeared some 3.0–2.3 billion years ago, and have not evolved much

The reflection and n-fold symmetry of functions of plane polar coordinates are defined. It is shown that the Fourier series with respect to the angular coordinate expresses most obviously the symmetry properties of these functions; if a function has

The wavefunction of the Fraunhofer diffraction from sector stars (i.e. radial gratings, spoke targets, Jewell's tests, Siemens' stars) is derived. Particular features of the diffraction patterns are explained by means of both the derived mathematical

2D-models of disordered structures are studied by optical (Fraunhofer) diffraction. It is shown that medium-angle scattering effects, e.g. the first sharp diffraction peak in chalcogenide glasses and the prepeak in metallic glasses, are evoked by clu
