The apple of an electronic eye
Publication: WIRED
Date Published: Friday, May 13, 2005
Renfu Lu, adjunct associate professor of biosystems and agricultural engineering, is the lead researcher on a noninvasive apple-inspection project that uses lasers to "taste" pieces of produce to assess their internal qualities. "By measuring light scattering in the fruit, mathematical models can determine its firmness and sweetness," says Lu.

Apple Quality’s More Than Skin Deep
Publication: AGRICULTURAL RESEARCH MAGAZINE
Date Published: May, 2005
Renfu Lu, adjunct associate professor of biosystems and agricultural engineering, and Yankun Peng, MSU visiting assistant professor of biosystems and agricultural engineering, have developed laser vision prototypes that can "taste" pieces of produce to assess their internal qualities. “Nondestructive technologies for grading and sorting fruit by internal quality such as firmness and sugar and acid content are a top priority,” says Lu. “Such technologies would ensure a consistent premium quality product, increase consumer satisfaction, and enhance the U.S. fruit industry’s competitiveness and profitability.”
