An experimental microwave imaging prototype for food quality assessment

Research on microwave imaging techniques for various applications has received growing attention over the past two decades. One of the potential applications of microwave imaging is food quality testing. Rapid worldwide increase in food demand and consumption requires development of novel non-destructive methods to both reduce the product wastage and increase consumer safety. This paper presents our first imaging results using a limited view microwave radar imaging prototype. Potato samples were used as material under test and image processing has been performed through a Huygens based algorithm. We show that our experimental prototype can detect potato defects, thus paving the way for several food quality assessment applications.
