VIPICO RESOURCES
Technical Resources for Non-Contact Vibration Measurement
Engineering articles on laser Doppler vibrometry, scanning measurement, modal analysis, damping identification and structural-dynamics applications.
KNOWLEDGE BASE
Methods, Selection Boundaries and Application Workflows
Each article states the measurement conditions and limitations that influence the result. The objective is to help engineers select an appropriate method, prepare a useful enquiry and interpret non-contact vibration data with fewer hidden assumptions.
