Ryan S. Thompson, Deposition Sciences Inc.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 the Centers for Disease Control. The Food Safety Modernization Act, signed into law in early 2011, was written to strengthen the food safety system by boosting the US Food and Drug Administration’s ability to be more proactive in managing the nation’s food production industry. Improving online food inspection techniques will go a...Read full articleRelated content from Photonics MediaARTICLESHigh-Speed Imaging Capabilities and Applications ExpandFast and efficient delivery of product into the customer’s hands is the endgame in manufacturing.
