Laser Doppler Vibrometry (LDV) uses the Doppler effect to measure the velocity and displacement of vibrating surfaces without physical contact. The laser beam reflects off the surface, and the frequency shift in the returned light is directly proportional to the surface’s velocity. This makes LDV invaluable for vibration testing in fields like:

• Aerospace: For non-destructive testing of complete aircraft as well as critical components, ensuring structural integrity.

• Automotive: To evaluate NVH (noise, vibration, and harshness) characteristics.

• Rotary Machinery: To asses
