Frequently Asked Questions about Laser Doppler Vibrometer

The measurement range of the LV-1710/LV-1720A is represented by a tripartite graph with four axes representing the three elements of vibration (displacement/velocity/acceleration) and frequency. If two of the measured values—frequency (Hz), displacement (m), velocity (m/s), and acceleration (m/ ^s²)—are known, the other two values can be determined. If the intersection point of the two known values falls within the measurement range of the respective model, it can be determined that the device is usable.
