Bringing the minefield to the detector: updating the REST concept

REST is a vapour collection technology with many potential detection applications, including area reduction in demining. As part of a broader programme of research on mine detection animals, the GICHD is supporting a range of research initiatives on REST. The key elements of REST are identified as sampling (procedure and equipment); storage, transfer and handling of filters; training of the detector; and ensuring reliability in the analysis process. Recent contributions to understanding of each of these elements are reviewed. REST has great potential as an area reduction technology, but challenges that must be overcome before it will be implemented include conservatism in the demining industry, funding constraints, limited interest in REST as a research problem, limited expertise and capacity, and defined standard operating procedures.
