Paper Abstract

In this paper, vibration monitoring and measurement carried out in the newly developed nanometer metrology laboratory in Birmingham University, is described with respect to measurement methods and instrument performance. Two types of instrument -- piezoelectric accelerometer (B&K type 8318 with a type 2140 bus-controlled frequency analyzer) and laser interferometer (Renishaw ML10 laser interferometer with the Keithley multi-channel FFT analyzer) were used in vibration measurement on capability verification of a vibration isolation system. Vibration results from a concrete block are presented. From the point of view of the measured vibration results, it is demonstrated that the performance of the above two instruments is not completely the same in the different frequency ranges. The related comparison and discussions are presented in this paper.
