Laser Doppler Vibrometer
As we all know, the measurement and analysis of vibration characteristics is an important measurement method to identify and confirm the quality characteristics and working conditions of machines and components. Non-contact laser Doppler vibrometer technology based on the principle of laser interferometry has gradually become the most important vibration measurement method due to its better displacement and velocity measurement resolution, and has been widely used in basic science and engineering measurement fields.

Laser Vibrometer + Thin Film Cantilever Beam Test Fixture
The laser vibrometer combined with the Thin Film Piezoelectric Test (E31) allows the measurement of the piezoelectric coefficients (E31, D31 and E33) of piezoelectric films deposited on the cantilever. Voltage applied to the piezoelectric film causes the substrate to bend in all directions. The displacement is measured by the laser test vibrometer at high speed. Measurements made with the Thin Film Piezoelectric Test Kit include (but are not limited to): E31, D31, D33, E33 and Thickness Displacement vs. Voltage. |
