Modular software platform for low-dose electron microscopy and tomography.

Transmission electron microscopy imaging protocols required by structural scientists vary widely and can be laborious without tailor-made applications. We present here the jeol automated microscopy expert system (james) api integrator, a programming library for computer control of transmission electron microscopy operations and equipment. james has been implemented on JEOL microscopes with Gata...

Electron Diffraction Based Tilt Angle Measurements in Electron Tomography

Electron tomography can provide three dimensional (3D) visualization of nanoscale objects in a transmission electron microscope (TEM) from a tilt series of projected images. The accuracy of the 3D reconstruction depends on quality of input parameters, including accurate alignment in real space and accuracy of tilt and azimuth angle measurements. Here we present an electron diffraction-based in-...

Electron Diffraction Electron Diffraction

This guide sheet outlines a method for the analysis of cubic crystal forms, this being useful to you for interpreting the transmission diffraction pattern produced by scattering electrons off a thin film target of polycrystalline aluminium. The apparatus also contains samples with hexagonal structures. These are pyrolytic graphite targets, and are available both as single crystals and in polycr...

Rapid low dose electron tomography using a direct electron detection camera

We demonstrate the ability to record a tomographic tilt series containing 3487 images in only 3.5 s by using a direct electron detector in a transmission electron microscope. The electron dose is lower by at least one order of magnitude when compared with that used to record a conventional tilt series of fewer than 100 images in 15-60 minutes and the overall signal-to-noise ratio is greater tha...

Low sidelobe limited diffraction optical coherence tomography

Optical Coherence Tomography (OCT) is a relatively new type of imaging system for medical diagnosis. Because most current OCT systems use a sharply focused beam in tissues, they have a short depth of field (high image resolution is near the focus only). In this paper, limited diffraction beams of different orders are used to increase depth of field and to reduce sidelobes in OCT. Results show t...
