Laser Vibrometer from DYNEOS AG

Our laserinterferometric vibrometers are ideal instruments for accurate, noncontacting, determinations of temporal changes in the positions of objects or surfaces and allow detecting mechanical vibrations at frequencies ranging from 0 to 500kHz. These instruments have been designed based on the proven concept of our SP-Series miniature plane-mirror interferometers. The sensor heads of Series SP-S interferometers are equipped with additional optics that allow making measurements on surfaces having arbitrary roughnesses.

The complete system consists of a modularly designed electronics unit incorporating a He-Ne-laser, a compactly designed sensor head, and various interfaces. Their fiberoptic-coupled interferometer converts motions along their optical axes into interference fringes that are transmitted to their fast, high-resolution, demodulation electronics for processing. Operation and display of results employs a PC running specialized data-analysis software.
