HIGH PRODUCTION NON-DESTRUCTIVE X-RAY TESTING EQUIPMENT FOR INDUSTRIAL PRODUCTION LINE MONITORING WITH ON-LINE COMMPUTER EVALUATION

Ziel

The aim of the proposal is the investigation and the development of an automatic X-ray NDT analysis using a new sensor concept with customised integrated pulse handling and readout together with special multichannel image processing.
The development of an X-ray testing equipment for nondestructive industrial production line monitoring was successfully finished with a prototype which demonstrates the properties of the machine.

Compared to existing equipment the main progress was made in:
a new detector technology which also required new basic efforts in crystal growing;
a new kind of integrated multiplexing preamplifier;
versatile image processing modules;
appropriate software packages;
a mechanical and electromechanical layout which matches the needs of the users.

Use of the X-ray testing equipment is already envisaged in:
detection of melted centres in insulation rock wool;
inspection of foam materials for holes or foreign material;
detection of holes or foreign material in potatoes;
detection of foreign material (especially metal) in napkins.
This approach makes use of energy selective X-ray sensors associated with a low noise linear integrated electronics as well as an integrated image processing system. The main tasks are :

-research and development of cadmium telluride energy selective sensors built together in blocks of up to 1500 elements
-specification and design of a suitable integrated preamplifier followed by other integrated pulse handling electronics adapted to these sensors
-design and development of a flexible X-ray generator adapted to both sensor and scanning technologies
-concept and prototype development of special image processing hard- and software to handle the multidimensional data delivered by the material discriminating NDT system
-integration of the components to a prototype system to verify the functionality.
