Method and device for scanning of objects using a combination of spectral ranges within vision, near infrared light and x-rays

Abstract

The method and equipment described are for coherent scanning, that is where sections of the same object are comparable in the images, of objects such as food stuff based on scanning with the utilization of electromagnetic waves from at least two ranges within vision (visible light), NIR (near infrared light) and X-rays. The method consist of determination an object's reflection in the NIR and/or vision ranges associated with the same object's transmission in the X-ray range to obtain an even higher degree of details concerning the structure of the object by determining its surface texture together with description of its inner structure and/or composition. The equipment comprises a cabinet (), a computer (), a camera (), an X-ray source (), a light source (), and an X-ray detector (). An additional start sensor () registers the presence of objects on the conveyor belt () and the scanning is triggered.
