Scanning Projection Grating Moire Topography
One problem with moiré topography for 3D surface metrology is the so called 2π-ambiguity limiting the maximum step height difference between two neighboring sample points to be less than half the equivalent wavelength of moiré fringes. To cope with the ambiguity problem, a special scheme of scanning moiré technique is proposed by resorting to the frequency domain fringe analysis that is in fact...
متن کاملEvaluation of scoliosis screening using Moire topography in school children
Objective Screening of school children for scoliosis is an orthopedic examination that has a direct effect on the health of these children. Screening can be performed using various methods. Since 1983, in our prefecture, we have used Moire topography for screening. The purpose of this study was to evaluate the prevalence rate of scoliosis diagnosed by screening school children using Moire topog...
متن کاملEtching of sub-micrometer structures through Stencil
The processing techniques for micro and nano devices fabrication can be divided into two groups. On one hand, there are the techniques that allow the modification of a given substrate, e.g. ionic implantation, metallization, etching and thermal processes to either grow or deposit insulator layers. On the other hand, there are the processes that allow a pattern transfer of the designs onto the s...
متن کاملIsolation of Microorganisms Using Sub-Micrometer Constrictions
We present an automated method for isolating pure bacterial cultures from samples containing multiple species that exploits the cell's own physiology to perform the separation. Cells compete to reach a chamber containing nutrients via a constriction whose cross-sectional area only permits a single cell to enter, thereby blocking the opening and preventing other cells from entering. The winning ...
متن کاملOrganic Fluorescent Nanofibers and Sub-micrometer Rods
Luminescent nanofibers are a particular class of nanofibers. Like the other members of this family, they are very small objects whose typical diameters range between 50 to 500 nm (it is noteworthy that beyond these values, the term of microfibers is more appropriate) and lengths can reach several hundred micrometers. Besides, they display special photophysical behavior. By definition, fluoresce...
