Interferometric techniques for the precIsIon measurement of length have found increasing application since the turn of the century. With the advent of compact laser systems of narrow spectral bandwidth and corresponding high coherence. In fluid mechanics, non-intrusive measurements are fundamental in order to improve knowledge of the behavior and main physical phenomena of flows in order to further validate codes.

The principles and characteristics of the different techniques available in laser metrology are described in detail in this . The technique yields information about sound veloci- ties, modulus of elasticity, film thick- nesses, interface . Femtosecond Lasers for Precision. Frequency and Distance Metrology. Head of the Institute of Photonics and Quantum Sciences. School of Engineering and Physical Sciences. Focus of the first three days is on instrumentation and the second part of the workshop on refractivity compensation and turbulence.

One major outcome of this workshop is to come to research strategies for the. Lecture Contents Laser Metrology. The use of lasers in metrology includes the precise measurement of distance, velocity, acceleration, torque, strain, surface finish, and shape.

The two high-reflectivity mirrors of the Fabry–Pérot cavity will be suspended separately by two nearly identical simple pendulums of length about.
