Time resolved electron microscopy
A secondary electron puddle is characterized by its spatial location, its two-dimensional (2D) shape, and the pixel intensities within this shape. To accommodate various downstream processing needs we define four logical data reduction levels: L1, L2, L3, and L4, with progressively higher levels of file size … See more An appropriate threshold separating signal from noise is critical for electron counting to be effective. Typically, this threshold is established through calibration, based on dark and gain references obtained during data acquisition. In … See more With increasing electron flux, the data naturally becomes less reducible and less compressible. To quantify this change, we simulated images at eight electron fluxes between 0.0025 to 0.07 e/pixel/frame (Fig. 3). This range … See more Any lossless compression algorithm can operate on the reduced data levels in Fig. 1. Compression algorithms are either optimized for … See more Electron microscopy imaging often has to be performed at low electron flux to reduce beam induced damage, if the sample is dose sensitive, as well as to minimize beam … See more WebDec 12, 2024 · X-ray microscopy offers resolutions down to around 60 nm, and spatial resolutions of around 20 nm have been obtained by super-resolution microscopy; therefore, it is important for time-resolved electron microscopy to capture high-speed phenomena that occur at spatial scales of under 100 nm because these cannot be measured by laser or X …
