High-resolution study of the giant viruses presents one of the latest challenges in cryo-electron microscopy (EM) of viruses. Too small for light microscopy but too large for easy study at high resolution by EM, they range in size from ∼0.2 to 2 μ

The Darwin-Howie-Whelan equations are commonly used to describe and simulate the scattering of fast electrons in transmission electron microscopy. They are a system of infinitely many envelope functions, derived from the Schr\"odinger equation. Howev

Over the past years, the single-frequency and single-sensor microwave imager using programmable metasurface, called programmable microwave imager for short, has attracted researchers’ attention because of its unique advantages over conventional ima

A pixel-based approach for extracting structure factors from X-ray free-electron laser crystal diffraction measurements is presented.
Most crystallographic data processing methods use pixel integration. In serial femtosecond crystallography (SFX

The Gaussian beam concept allows to produce well focused propagating plane-wave fast multipole translation operators, where many of the plane-wave samples with small magnitudes can be dropped during the computation of the fast multipole spectral inte

In optical metrology various approaches have been made in order to push the physical limitations of lateral resolution in microscopic and interferometric devices. Microsphere-assisted interferometry enables the measurement of structures well below Ab

One of the primary uses for transmission electron microscopy (TEM) is to measure diffraction pattern images in order to determine a crystal structure and orientation. In nanobeam electron diffraction (NBED) we scan a moderately converged electron pro

We present a general theory of optical coherence tomography (OCT), which synthesizes the fundamental concepts and implementations of OCT under a common 3D k -space framework. At the heart of this analysis is the Fourier diffraction theorem, which rel

We develop an algorithm capable of imaging a three-dimensional object given a collection of two-dimensional images of that object that are significantly influenced by the curvature of the Ewald sphere. These two-dimensional images cannot be approxima
