Abstract: In this article, we propose a laser-magnetic focusing electromagnetic acoustic resonance (EMAR) (laser-MFEMAR) method for flaw detection at large lift-off. This method effectively addresses ...

MKS INSTRUMENTS Newport 819-SL-06-WL optical power and wavelength sensors provide accurate, real-time power and wavelength measurements of laser sources between 400 and 1100nm. Calibrated to NIST ...

This paper proposes the measurement method for the surface profile of aero-engine blades based on multi-line laser sensing, which demonstrates excellent applicability for the 3D surface measurement.
