Food manufacturers still struggle with the contamination of their products by foreign bodies today. They must first assure customers that their pur- chases are safe. Second, contamination can harm a company’s brand and result in pricey recall efforts. Lastly, because accurate foreign body detec- tion technologies enable manufacturers to acquire essential food certifications that may boost their revenues. The issue of metal object detection is a major concern for a variety of industries. To address this issue, a number of strategies have been imple- mented, such as signal processing filters, detection systems, X-ray scanning, and near-infrared imaging. However, these strategies have some limitations, such as susceptibility to water attenuation, and a trade-off between low spatial resolution and high penetration depth.
