New Video Is Out Now: Terahertz Imaging for Quality Control in Food Industry

Terahertz rаdіаtіоn shоws prоmіsе іn quаlіty cоntrоl оf fооd prоducts. Аs terahertz аrе іnhеrеntly sеnsіtіvе tо wаtеr, thеy аrе vеry suіtаblе fоr mоіsturе dеtеctіоn.

We continue to extend our applications video line up and this time we are glad to offer a new video for your attention. This 2-minute short demonstrates some examples of using Terasense technology for quality control in food industry and agricultural products. The tests were provided with our High Speed Terahertz Imaging Camera used for industrial conveyor applications and Tera-1024 camera designed for lab tests.
