Researchers at Purdue University have built an imaging application to detect suspended dust concentrations that pose a risk of exploding in agricultural, powder-handling, and manufacturing settings. The application establishes a relationship between the light extinction coefficient and suspended dust concentration. It uses a camera or video recording device to image and determine suspended dust concentration in a daylight environment and to distinguish it from normal background noise. After capturing images of the suspended dust cloud, the application analyzes the light extinction...Read full articleRelated content from Photonics MediaARTICLESNSF Grant to Advance Sensing and Imaging Technologies for Precision AgricultureWith a five-year, $26 million grant, the National Science Foundation (NSF) has established the Engineering Research Center for the Internet of Things for Precision Agriculture (ERC IoT4Ag).
