Farmers Fuel Growing Market for Imaging Systems
Jun 1, 2013 — As imaging systems improve, they are increasingly taking to the fields and the skies to send back crucial pictures of crop health. Climate change, population growth and increasingly scarce resources are putting agriculture under pressure....
SERS Susses Out Salmonella
ATHENS, Ga., April 11, 2012 — In the future, even the smallest traces of salmonella and other foodborne pathogens may be easily detected using a technology known as surface-enhanced Raman scattering, or SERS.
Optical Filters Take Food Inspection to a Whole New Level
Jul 1, 2011 — Multispectral machine vision systems are one way to speed up quality control on production lines – and to make sure our food is safe for consumption. Foodborne diseases affect approximately 48 million people in the US each year, according to...
Measuring the Earth from Above: 30 years (and Counting) of Hyperspectral Imaging
Jun 1, 2011 — Hyperspectral remote sensing, in which an entire spectrum is acquired at each pixel of an airborne or orbiting sensor, provides a more complete understanding of the Earth’s surface and is a tool for monitoring change. Unlike multispectral...
Laser ‘Tattooed’ Fruit Label
WASHINGTON, Sept. 3, 2009 – Those small and sometimes inconvenient sticky labels on produce may eventually be replaced by laser etching, a new technology being tested by the Agricultural Research Service and University of Florida that puts tattooes on grapefruit and other...
UV LEDs Enrich Lettuce
WASHINGTON, May 18, 2009 -- Exposure to light provided by ultraviolet LEDs makes lettuce darker and redder, boosting the levels of healthy antioxidants it contains, according to a team of plant physiologists. Steven Britz of the US Department of Agriculture in Beltsville,...
