In this work, project partners will develop several new measuring tools and techniques that are capable of operation in typical industrial LVM environments and which are based on several different operating principles, to maximise the range of applications where they can be used. We plan to work towards measurement volumes of 10 m x 10 m x 5 m to a target accuracy of 50 µm.
To ensure future traceability to the SI metre is maintained and accessible in end-user environments, we will develop new traceable absolute distance meters (ADMs) to operate over ranges of at least 20 metres, specifically a portable line-of-sight ADM and one built into a tracking interferometer.
Almost all LVM instruments are optical-based and therefore affected by air refractive index and refractivity gradients. We will develop both line-of-sight refractive index measuring systems as well as a novel system that can measure refractive index effects over a 3D volume. These systems will enable on-line compensation of refractive index effects in industrial environments over volumes up to of 10 m x 10 m x 5 m with a target accuracy of 1 part in 107.
In this WP we will undertake the necessary modelling to understand and predict how large multi-component structures (such as aircraft wing segments) behave in non-ideal measurement environments.
The capabilities of the developed new technologies, instruments and approaches will be verified and demonstrated using measurements at partner laboratories, and in real-world industrial environments. In particular, tests at Airbus and at the AMRC are envisaged.
This website is one route to impact, but several others are planned: articles in trade press, presentations at trade fairs/industrial conferences, a suite of technical papers in peer reviewed journals, frequent progress reports to EURAMET TC-L and the CIPM Consultative Committee for Length, industrial focused workshop, NPL Good Practice Guide, stakeholder committee and intellectual property licensing.
The research within this EURAMET joint research project receives funding from the European Community's Seventh Framework Programme, ERA-NET Plus, under Grant Agreement No. 217257.
The project ends on 31 May 2016.
09:00 Wednesday 18 May 2016 to 14:00 Thursday 19 May 2016
The workshop was held at the National Physical Laboratory, Teddington, TW11 0LW, UK.
