A new laser-optical system uses 2,000 controllable beams to precisely position atoms, enabling key logic processes in a ...
A laser pointer shining on a diffraction grating or CD creates a series of diffraction spots depending on the spacing of the lines or pits in the grating or CD and the wavelength emitted by the laser.
Materials scientists at Rice University have developed a new workflow methodology for measuring microscopic defects in ...
Unlike almost every other kind of microscope, atomic-force microscopes (AFMs) don’t use any kind of optical beam to image ...
When viruses travel through the air in tiny droplets, they can quickly start to dry out. Yet many viruses remain infectious after rehydration—something that is still not fully understood. Now, an ...
IF a fine beam of homogeneous cathode rays is sent nearly normally through a thin celluloid film (of the order 3 × 10 6 cm. thick) and then received on a photographic plate 10 cm. away and parallel to ...
