Background: Because of their precise nature, interferometric measurements are
sensitive to vibration. Vibration can occur from rotating machinery, nearby traffic,
acoustic noise and a variety of other sources. Touching the instrument or the surfaces on
which it sits during measurements can also affect the measurements.
Instrument placement considerations: The instrument should be placed on a solid
support away from obvious sources of vibration (e.g. rotating machinery). Ideally, the
instrument should rest on a separate surface so that vibrations from using the computer
keyboard and vibrations from other activities are not transferred through the surface to
the instrument.
Vibration Isolators: If the vibration is present even after the instrument is located on
its own surface away from vibration sources, then additional vibration isolation needs to
be employed. A low cost solution for vibration isolation is to place the instrument on a
piece of vibration isolation material such as Sorbothane. More sophisticated vibration
isolation tables are available from manufacturers such as Newport, Herzan, and
Technical Manufacturing Corporation (TMC). Before purchasing equipment, a technical
representative of the isolation equipment supplier should visit the site where the
instrument is installed to recommend the appropriate equipment to isolate the instrument
from the vibration sources present.
