HISER at symposium "Advanced Environmental, Chemical and Biological Sensing Technologies" in USA

SPIE holds for “Society of Photo-Optical Instrumentation Engineers” and is an American not-for-profit society for optics and photonics technologies since 1955. It organizes technical conferences, trade exhibitions, and education programs for researchers and developers in the light-based fields of physics, including optics, photonics, and imaging engineering. Within the framework of these topics SPIE organized the largest and most important conferences everywhere.

Baltimore, April 2016

The symposium “Defense + Commercial Sensing (DCS)” is a set of conferences - in the past mostly hosted in Baltimore but with a designated 3-year rotation among Anaheim (California, 9 - 13 April 2017), Orlando (Florida, 15 - 19 April 2018), and Baltimore (Maryland, 14 - 18 April 2019) as of 2017.

The 2016-DCS consisted of 56 conferences with a total of over 5.000 participants and 2.000 presentations. The RTT/GAIKA contribution on behalf of HISER was embedded in SPIE-9862 (Advanced Environmental, Chemical, and Biological Sensing Technologies XIII), Session 3: Hyperspectral Techniques, and titled

Challenges in automatic sorting of construction and demolition waste by hyperspectral imaging

Abstract

There is great potential for recycling of construction and demolition waste (C&DW) materials since they content valuable resources. But new C&DW is more complex than existing one and there is a need for shifting from traditional recycling approaches to novel recycling solutions. One basic step to achieve the objective is an improvement in sorting technology. Hyperspectral Imaging (HSI) is a promising candidate to support this process. The study describes experimental results with regard to detection of important C&DW material composites by VIS-NIR-HSI and a development path for an industrial implementation in automatic sorting lines.

The talk was well attended and followed with interest - in particular by experts from the mining industry; it was the only presentation touching the field of sensor-based sorting of C&DW at DSC-2016. The second issue is yet another reminder how much the whole issue is still underestimated in overseas and other where and stresses the pioneering role of the EU-initiative HISER. The full text of the paper can be read in Proceedings of SPIE Vol. 9862, doi 10.1117/12.2220769.

The project has received funding from the European Union's  Horizon 2020 research and innovation program under grant agreement No 642085.
