title: The elimination of building vibration in an optical laboratory.
abstract: The elimination of vibration is a straightforward engineering job that is analogous to the design of an electrical filter. The building vibration, which was so intense that no serious interferometry was possible, was measured using a commercial vibration meter. A simple, single-mesh mechanical filter was designed to remove the existing frequencies of vibration. The filter was constructed and its performance measured. As a practical test of the performance of the vibration elimination, a hologram was made on the vibration isolated granite slab.
