Identification of Vibration Events in Rotating Blades Using a Fiber Optical Tip Timing Sensor

open access: yesSensors, 2019
The blade tip timing (BTT) technique has been widely used in rotation machinery for non-contact blade vibration measurements. As BTT data is under-sampled, it requires complicated algorithms to reconstruct vibration parameters.

Turbocharger blade vibration: Measurement and validation through laser tip-timing [PDF]

open access: yes, 2012
High Cycle Fatigue (HCF) of turbine blades is a major cause of failure in turbochargers. In order to validate changes to blades intended to reduce fatigue failure, accurate measurement of blade dynamics is necessary. Strain gauging has limitations, so an
