Purdue spectroscropy

Purdue University researchers are using spectroscopy to determine the various compounds that make up a plant, and through that information, identify disease and insect infestations before the plant shows any symptoms visible to the naked eye. Graduate student Raquel Peron (shown at right taking the spectral profile of a leaf) has been developing the technique in the research group of Purdue entomologist John Couture, Ph.D. Also shown are Kristin Sauder (left) and Marguerite Bolt, who are capturing the measurements and analyzing the data quality. (Photo credit: Taylor Nelson)
