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 ...

When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording ...

Fresnel diffraction describes the complex light propagation that occurs when a wavefront encounters an abrupt phase change, typically at the boundary of two different media or at an engineered phase ...

Researchers at the University of California, Los Angeles (UCLA) have developed an optical computing framework that performs large-scale nonlinear computations using linear materials. Subscribe to our ...

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 ...

Review of the basics of Fourier optics and especially probability and random process which are fundamental to a correct understanding of random signals and noise. The noise and coherence of lasers and ...

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 ...

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 ...

Providing accurate alignment for any four-corner application requiring 90° angles, a line of diffractive optical elements can split or reshape light to almost any desired distribution. With a light ...

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 ...
