QImager

The QImager device is the result of an EU-funded project from the European Regional Development Fund.

Project title: Development of an innovative device for real-time non-invasive optical quality control of packaging production.

The project has developed a unique prototype device for non-invasive optical quality control in packaging production. As a component of already existing production machines, it provides an advanced interface in the operator-machine system. The machine operator, via the control panel, is able to configure the production quality verification process, view tomographic images in real time and react to errors in the technological process. Thanks to the integrity of the device with the production line, the high quality of image and sensitivity of the designed detection system and real-time quality parametrisation, among others, Scoptonic has introduced a new standard in quality control to the market. In order to achieve its goal, the company established cooperation with a team of scientists led by Maciej Szkulmowski, Ph.D., from the Nicolaus Copernicus University in Toruń, who carried out part of the industrial research planned in this project.

Value of the project: 2 966 637.14 PLN
Contribution from the European Funds: 2 280 954.59 PLN

Technology description and applications

The technology developed by the Scoptonic Team is based on Optical Coherence Tomography using partially coherent light from the infrared range. The light generated by the device illuminates the sample under examination. As it penetrates deep into the test object, it reflects or scatters from its individual layers. The light returning from the object is recorded and digitally processed to produce a final three-dimensional image with cross-sectional information. The technology produces images similar to ultrasound. However, unlike ultrasound, light waves are used instead of sound waves, that allow for non-contact examination. Due to the use of interference techniques, QImager is characterized by high sensitivity, and parallel signal recording allows real-time images to be obtained.

Below is an example of one tomogram showing the cross-section of a joint at the boundary of two material fragments. QImager technology allows to verify the quality of the joint.

The device can be used for package leakage testing in the food and pharmaceutical industries.
