ESR 1.2 Frequency Scanning Interferometry (FSI) For each distance to be measured, a measurement interferometer is built using optical components placed at each end of a line-of-sight. The optical path of each measurement interferometer is compared to the optical path in a reference interferometer, by scanning the frequency of a laser (connected to all interferometers in the system) and counting fringe cycles produced in the return signals from each interferometer.
ESR 1.2 • Tasks: • To develop the fiducials allowing the centring of optical fibre in order to perform absolute measurements (fiducials measurable by 3D CMM and usable for FSI) • Definition of requirements • Evaluation of solutions and conclusions [M18 – February 2015] M1-5 • To study different configurations of FSI network through simulations in order to choose the best one for the measurements sequences, prepare the design • To upgrade the FSI method (several reflectors seen by the same measurement channel)[M25 – September 2015] D1-4 • Inter-comparison with Micro-triangulation (in collaboration with ESR1.3) • Propose a test setup for comparison • Perform measurements • Analysis of inter-comparison • Integration and measurement on the Final Prototype Alignment Bench [M36 – August 2016] M1-6, D1-5 • Extrapolation to portable solution • Role of Etalon: • Training on equipment • Supervise integration, project proposal and calibration strategy • Provide calibration test stand? • Role of ETH Zürich: • Academic supervision
