High-tech approach uses lights, action and camera to scrutinize fresh produce
Date:5/10/2011

The system combines information from both forms of illumination into a single image with contaminant and defect results. When linked to a sorting machine, the system can signal the sorter to separate the problem apples from others.

At present, the system offers, at the rate of about 3 to 4 apples per second, a 180-degree view of each apple's exterior, Kim reports. The scientists are working to improve the process so it will provide a 360-degree whole-surface view for thorough inspection.

Preliminary findings from this work appeared in a 2008 issue of the journal Sensing and Instrumentation for Food Quality and Safety.
