spatial resolution News
Algorithm Targets Microscope Resolution
BOSTON, Nov. 16, 2023 — Scientists have used various approaches to improve spatial resolution in fluorescence microscopy. Deconvolution, in which images are numerically deblurred based on a knowledge of the microscope’s point spread function, is one approach....
Hyperspectral Method Adds Speed, Accuracy to Wafer Inspection
SEOUL, South Korea, April 26, 2022 — A high-throughput metrology technique for semiconductor manufacturing, developed by Samsung Electronics, combines spectroscopy and imaging to measure in-cell uniformity (ICU) and in-wafer uniformity (IWU) of semiconductor devices used in high-volume...
New Algorithms Improve Lensless Microscopes
ST. PETERSBURG, Russia, and TAMPERE, Finland, Aug. 15, 2017 — Using special algorithms scientists have significantly improved computational imaging of the optical signal in lensless microscopes. The algorithms not only generate the image, but also improve the optical signal, making it possible to obtain images...
Nanoscope Can Probe Chemistry on the Molecular Scale
BERKELEY, Calif., and BOULDER, Colo., May 9, 2014 — The in-depth study of complex molecular systems, from batteries and electronic materials to living cells and even stardust, is now possible with a new imaging technique. Broadband IR synchrotron light has enabled researchers at Lawrence Berkeley...
X-ray Camera Has Image Stabilizer
BERLIN, Jan. 8, 2014 — Making a firm connection between an x-ray lens and the nanoscale object to be imaged improves the imaging of low-contrast or moving nano-objects and could lead to new insights into dynamic nanoscale processes, such as the fastest magnetic switching...
Nanoantennas Form Ultrathin Holograms for Sensing
WEST LAFAYETTE, Ind., Nov. 18, 2013 — An ultrathin hologram — only 1/23rd the width of the light wavelength used to create it — could make possible light-based devices and optical switches small enough to be integrated into computer chips for advanced sensors,...
Raman Scattering Sped Up for Microscopy
GARCHING, Germany, Oct. 18, 2013 — Improvements to Raman spectroscopy using laser frequency combs allow multiple signals from different parts of a molecule — or even different molecules — to be monitored simultaneously using a single detector. The advance is seen as a...
Bodkin Design Issued Hyperspectral Imaging Patents
NEWTON, Mass., July 1, 2013 — Bodkin Design & Engineering (BD&E) LLC has received two US patents for enhancements to its nonscanning hyperspectral imaging product line. US Patent Nos. 8,174,694 and 8,233,148 support technology implemented for high-speed collection of 3-D...
NIR Imaging Gets Big Boost
STANFORD, Calif., Dec. 3, 2012 — Studying arterial diseases and therapies just got easier, thanks to a new fluorescence imaging technique that allows researchers to visualize the blood flow of living animals with unprecedented clarity. The Stanford University technique, called...
Photoacoustic Imaging Moves into Clinic
ST. LOUIS, March 26, 2012 — Photoacoustic tomography, which combines the best qualities of ultrasound and light absorption, can now provide clinicians with multicontrast images of biological tissue several inches below the skin’s surface.
Genetic tags illuminate life
SAN DIEGO – A new type of genetic tag made by modifying a plant protein has the potential to illuminate life in never-before-seen detail. Scientists from the University of California, San Diego (UCSD), School of Medicine have re-engineered a...
Unprecedented Spatially Resolved Chemical Analysis Via Nanoscale Spectroscopy
Dec 1, 2010 — The phrase “lab on a tip,” referring to nanoscale property measurements made by the probe of an atomic force microscope (AFM), has been a dream for the developers of analytical instrumentation. There also has been a drive for...
Electron-Multiplying CCD for Lidar Applications
Aug 1, 2010 — Until recently, only photomultiplier tubes were suitable for low-light imaging. However, this technology and associated poor spatial resolution were not suited to scientific applications. Solid-state devices such as image intensifiers or...
50 Years of the Laser Industry
Jun 7, 2010 — The relentless innovation that has always characterized the laser industry is now driven and firmly controlled by the needs of applications. In the technology’s infancy, the main goals were the discovery of new laser materials and the...
Endra Launches Imaging System
ANN ARBOR, Mich., April 21, 2010 — Endra Life Sciences has announced the launch of the Nexus 128, a photoacoustic computed tomography scanner for small animal imaging. The system is used for simple, fast and noninvasive quantification of tumor vasculature and other physiological...
Quantum Gases Made Visible
MAINZ, Germany, Oct. 22, 2008 – Scientists at the Johannes Gutenberg University Mainz have, for the first time, succeeded in rendering the spatial distribution of individual atoms in a Bose-Einstein condensate visible. Bose-Einstein condensates are small, ultracold gas clouds...
Sensor Peers into Electrons
CAMBRIDGE, Mass., Oct. 1, 2008 -- Physicists have exploited a special "flaw" in diamond crystals, manipulating them into monitoring magnetic signals from individual electrons and atomic nuclei and allowing scientists to spy on some of the universe's tiniest building blocks. The...
Spatial Resolution, Surface Roughness Improved in Laser Fabrication
Mar 1, 2005 — A research group at Osaka University in Suita, Japan, reports that the spatial resolution of two-photon polymerization laser fabrication and the surface roughness of objects created using the technique may be improved with the addition of radical...
Electron Multiplication CCDs Offer a Flexible Solution
Jun 1, 2004 — A recent advance in CCD technology is the introduction of electron multiplication or charge carrier multiplication CCDs. This technology is effective in applications requiring high light sensitivity, high spatial resolution and reasonably high frame...
Hybridizing Spectroscopic Techniques
Feb 1, 2004 — Any given material can be characterized using a wide variety of spectroscopic techniques, each of which provides useful information. Depending on the material in question, of course, some methods are more effective than others. For example,...
