Geometry scan unit
Staff -- Test & Measurement World, 5/1/2005
Used with the PSV-400 series of scanning vibrometers, the Geometry Scan Unit (GSU) combines a laser range finder with scan mirrors that position the vibrometer measurement beam to determine the 3-D geometry of test objects. After defining the measurement grid, but prior to measuring the test object's operational deflection shape, the GSU samples the grid and constructs a geometry file for the object. Within minutes, the 3-D geometry model of the structure can be plotted to a monitor giving a static baseline for observing the dynamic vibration of the object. Polytec, www.polytec.com.
