BLACKSBURG, Va., March 13, 2007 -- Producing optical images at resolutions as low as one nanometer is the goal of Virginia Tech College of Engineering researcher Yong Xu, who has received a National Science Foundation (NSF) Faculty Early Career Development Program (CAREER) award. Xu, an assistant professor of electrical and computer engineering, recently secured the five-year CAREER grant, which is worth $400,000; the awards recognize a young researcher's commitments to scholarship and education. “The resolution of most optical microscopes is restricted by the so-called ‘diffraction limit,’ which means we cannot...Read full articleRelated content from Photonics MediaARTICLESLow-light Photodetector Senses Shades from UV to NIRResearchers at RMIT University (Australia) introduced a hyper-efficient broadband photodetector capable of imaging all shades of light between the UV and near-infrared ranges and is at least...Photonics Spectra December 2020 IssueAll-Glass Fiber Optic Sensor Measures Force on Miniature ObjectsA team of researchers has designed a tiny fiber optic force sensor, approximately equal in diameter to a human hair, capable of measuring extremely slight forces exerted by small objects.

Since nanopositioning is a discipline that has enabled swiftly evolving application arenas as diverse as materials science, genomics, photonics, defense, biophysics, and semiconductors, it’s unsurprising that its pace of innovation is nothing short of blistering in recent years.By its original definition, a nanopositioning device is a mechanism capable of repeatedly delivering motion in increments as small as one nanometer. Lately demands from industry and research have...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookPositioning System Performance: Understanding the Rules: To make the right decisions and to ensure satisfactory performance in a positioning system, it is necessary to first have a grasp of performance parameters and an understanding of their definitions.Abbe Error — Linear off-axis errors introduced by angular deviations coupled to a moment arm at the point of interest on stage mounted devices (θ in Figure 1).
