  • Full-Scale High-Speed Schlieren Imaging Of Explosions And Gunshots (.pdf)
    described several schlieren arrangements having. extensive light sources, small lenses, and a resulting field-of-view roughly half the size of the light source. In his. schlieren method number 4, diagrammed in Fig. 1, a large source grid consisting of dark and bright lines is imaged by a. lens upon

  • MICRO: Products
    for 65-nm wafer inspection, the 302 system combines both bright-field and dark-field inspection technologies in one tool. For bright-field inspection, the system's Step &Image 2-D imaging technology replaces traditional TDI CCD technology, which is slow and jitter-prone. The system is also effective

  • Hubble Finds Intergalactic Stars
    NASA's Hubble Space Telescope has found a long sought population of "stellar outcasts" stars tossed out of their home galaxy into the dark emptiness of intergalactic space. This is the first time stars have been found more than 300,000 light-years (three Milky Way diameters) from the nearest big
