This meant that a microscope could not resolve two objects located closer than λ/2NA, where λ is the wavelength of light and NA is the numerical aperture of the imaging lens. This diffraction ...

In recent years, lensfree on-chip microscopy has developed into a promising and powerful computational optical microscopy technique that allows for wide-field, high-throughput microscopic imaging ...

Given the rapid expansion of genomic, transcriptomic, and microscopy tools available to the average neurobiologist, it is possible to select models for biological qualities that help address specific ...

This study introduces a multidimensional sampling theory, overcoming Nyquist limitations and enhancing metasurface design for advanced optical applications.

The OpenFlexture Microscope is a DIY, open-source, 3D-printed microscope built around the Raspberry Pi 4, a Raspberry Pi Camera Module v2, and a choice of optics or various qualities up to lab-grade ...

Researchers have designed and built the world’s first microscope made entirely from 3D-printed parts. And because the open-source plans are already available online, almost anyone can assemble ...

The numerical results are validated by experimental LPB imaging outcomes of (1) a static two-photon polymerization (TPP) printed phase object measured in a lensless DIHM setup and (2) a dynamic sperm ...

When selecting a microscope, it’s important to consider various features, such as the field of view, frame construction, lighting, optical quality and resolution. There are several types of ...

Starting from January 2025, this repository contains the source code for the book Fundamentals of Numerical Computation by Tobin A. Driscoll and Richard J. Braun. Previous editions were published by ...

While it's possible to let the camera handle it automatically, mastering the f-stop is crucial if you want to fully control your photography. Also known as aperture size, the f-stop controls the ...
