Summary
Frequency Scanning Interferometry (FSI) is a well-known one-dimensional absolute distance measurement technique. Recent research at the National Physical Laboratory (NPL) in the UK has focused on adapting FSI and combining it with multilateration to produce a traceable, self-calibrating 3D coordinate measurement system. This presentation will start by giving a brief overview of conventional FSI and show how we have been adapting it to operate with multiple targets simultaneously in 3D and how we have applied novel solutions to overcome the well -known vibration sensitivity of FSI and to increase the range of operation of a 3D FSI system.
