LOS ALAMOS, N.M., Sept. 26, 2006 -- Using an innovative sensor for detecting single photons, the smallest particles of light, scientists have set two significant distance records for distributing "keys" (or codes) for quantum encryption, the most secure method known for protecting the privacy of information. As described in the September issue of New Journal of Physics, the team from Los Alamos National Laboratory (LANL), the National Institute of Standards and Technology (NIST) in Gaithersburg, Md., and Albion College in Albion, Mich., generated and transmitted secret quantum keys over 184.6 km of fiber-optic cable, the...Read full articleRelated content from Photonics MediaARTICLESQuantum Technology and the OPI IndustryMark A.

Resolution, however, is a more complex concept.Camera resolution depends upon the optical blur diameter and the detector size.

The layer of gases that we breathe also distorts the images formed by telescopes. This means that conventional telescopes of more than a few centimeters in diameter cannot reach the resolution limit set by their optics.To Isaac Newton the problem was clear, and in 1704 he realized the effects of atmospheric turbulence on image formation. Just as heat waves shimmering above a hot patch of ground can distort our...Photonics HandbookWHITEPAPERSRecent Research Using Meadowlark Optics Spatial Light ModulatorsThis ever-evolving collection of recent research using Meadowlark Optics Spatial Light Modulators offers a brief overview of specific applications in which Meadowlark Optics’ Spatial Light Modulators...Photonics.com 9/4/2020Maximum Measurable Power for Photodiode DetectorPhotodiodes are one of the most common detectors used for measuring optical power of a light source.
