IT may be of interest to give a preliminary account of what I believe to be a new method of producing acoustic spectra. The method, which is to employ the striations on “variable-density” sound-film ...

Diffraction is a classic optical phenomenon accounting for the light propagation. The efficient calculation of diffraction is of significant value towards the real-time prediction of light fields. The ...

Despite the essential role crystal structure refinement plays in modern materials characterization, it remains a delicate manual undertaking involving trial-and-error ...

Description: Modern theories of diffraction and Fourier optics for imaging, optical communications, and networking. Imaging techniques involving diffraction and/or Fourier analysis with application to ...

Super-resolution (SR) fluorescence microscopy, through the use of fluorescent probes and specific excitation and emission procedures, surpasses the diffraction limit of resolution (200~300 nm) that ...

Typical spectrometers use prisms or diffraction gratings to spread light over a viewing window or digital sensor as a function of frequency. While both prisms and gratings work very well, there are a ...

This is a preview. Log in through your library . Abstract In scalar diffraction theory, an optical instrument can be treated as a linear system for the two limiting cases of coherent and incoherent ...

Chemical structure databases, such as the Cambridge Structural Database (CSD) and the Crystallography Open Database, are indispensable repositories of information for chemical research. These ...

Fluorescence microscopy techniques are powerful tools for probing very small signals and revealing three-dimensional (3D) structural and functional properties of biological samples with high ...

This article explains the reason why so many manufacturers need to measure particle size and the reason behind laser diffraction being the method of choice. Different industries measure particle size ...

Optical diffraction tomography (ODT) has long been recognized for its potential in non-invasive, label-free imaging of live biological cells. However, a major challenge arises when ODT is applied to ...
