What Is A Vibrometer? |
|
Answer» A vibrometer is generally a TWO beam LASER interferometer that MEASURES the frequency (or phase) difference between an internal reference beam and a test beam. The most common type of laser in an LDV is the helium–neon laser, ALTHOUGH laser diodes, fiber lasers, and ND:YAG lasers are also used.
