For Scanning Vibrometers
TUSTIN, Calif., April 8 -- Polytec Inc., a maker of scanning laser vibrometers for noncontact, experimental modal analysis, has introduced what it says is the first geometry scan unit for the PSV-400 series of advanced scanning vibrometer systems. Designed to experimentally determine the 3-D shape/geometry of test objects, the geometry scan unit (GSU) combines a laser rangefinder with the scan mirrors that position the vibrometer measurement beam. After defining the measurement grid but prior to measuring the test object's operational deflection shape, the GSU can sample the grid and construct 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. This is particularly useful when solid-model CAD data isn't available.
Both 1-D and 3-D versions of Polytec's scanning laser doppler vibrometers allow accurate visualization of a structure's vibrational characteristics without the inconvenience of instrumenting with an array of transducers. The new geometry scan unit adds even more convenience and value by permitting users a straightforward approach to determine the test object's geometry, to simplify the alignment of the three separate heads of the 3-D scanning vibrometer and to rapidly set measurement-head focus settings. Applications for the integrated system include automotive, aerospace and defense, transportation, steel fabrication, mechanical and civil engineering and R&D.
