Abstract

A portable Scanning Laser Vibrometer (SLV) is described which will measure the surface velocity of a vibrating object at locations on a user-defined grid of up to 64 × 64 points. This velocity information can then be displayed in slow motion on a standard laboratory oscilloscope or stored for analysis at a later date. The instrument is robust, compact, user-friendly, inexpensive and safe for use by an engineer on-site.
