Paper Abstract

A traceable standardized set up to measure vibrations by means of interferometry is described in the present work. For this purpose a Twyman-Green interferometer with expanded and collimated single beam was realized. Interference fringes are processed with the Minimum Point Method and displacement information is extracted. Vibration displacements in the micrometers range are easily observed and measured. Submicron resolution and micrometer accuracy are naturally obtained.
