WS-63C Digital Pen Vibrometer
1. Overview


A digital pen vibrometer is a small pen like instrument which measures the acceleration, displacement and velocity.Generally,vibrometer is 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.
