In this image, patterns captured at attosecond intervals have been superimposed, thus revealing, in real time, the kind of electron motions that underlie atomic and subatomic phenomena.
This motion would be detected by measuring image charges, which are induced by the moving electrons, flowing through another electrode using a commercially available current amplifier and lock - in detector.
Electron microscopy and electron diffraction can provide the spatial resolution to image atoms, but filming atomic motions requires ultrashort shutter speeds — the shorter the electron pulses, the sharper the images from the micrElectron microscopy and electron diffraction can provide the spatial resolution to image atoms, but filming atomic motions requires ultrashort shutter speeds — the shorter the electron pulses, the sharper the images from the micrelectron diffraction can provide the spatial resolution to image atoms, but filming atomic motions requires ultrashort shutter speeds — the shorter the electron pulses, the sharper the images from the micrelectron pulses, the sharper the images from the microcosmos.
«Other researchers use x-rays to capture atomic motions, so no one thought we could ever develop a bright enough source based on electrons as they undergo electron - electron repulsion and would blow up without being able to capture an image on the incredibly short time scale required,» says Miller.
In addition to the motion of the video image, the analog photographer must also be sensitive to the friction betweenthe camera's straightforward light - capture process and the CRT monitor's beams of magnetized electrons, which light up pixels within the screen to present a steady image to the human eye, but whose glow registers quite differently to the camera.
