Linear transforms — like a Fourier transform — are a key math tool in engineering and science. A team from UCLA recently published a paper describing how they used deep learning techniques to design ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

(Nanowerk News) Researchers have developed a new measurement and imaging approach that can resolve nanostructures smaller than the diffraction limit of light without requiring any dyes or labels. The ...
