THEME ONE

Embedded Metrology Foundations
WP3 Spectral Interferometers for Multi-property Measurement

The aim of this WP is to explore spectral interferometry as the basis for creating novel sensors operating at both long-scales (metres) and nano-scales. For absolute distance, vibration and surface topography measurement at the long-scale, the key targets are rapid coordinate measurement with low system cost. At the nano-scale, the challenge is to produce an ultra-miniature sensor-on-a-chip for absolute distance, surface profile and layer thickness measurement. This WP contributes to the aim to support embedded metrology ‘cross-scale’ in high-value manufacturing by aligning Theme I, Objectives 2 & 4.
