Ultrasonic Technology in the 21st Century

The History of OPUS


SoniSys, Inc. was founded by Dr. Pierre Brodeur in 2000 as a research and development company specializing in the field of dry contact ultrasonic technology for the testing of flexible materials.  His specialized knowledge of laboratory ultrasonic measurement applications for pulp and paper testing led to a National Science Foundation-SBIR Phase I and Phase II grant. 

With financial backing from the NSF, SoniSys was able to offer the first commercial non-destructive analytical instrument for measuring the strength and stiffness properties in the thickness direction of thin fibrous materials such as papers and plastics. This ultrasonic technology addresses a deficiency in existing mechanical fracture methods that suffer poor reproducibility and are tedious to perform. This instrument, designed specifically for out-of-plane measurements,  is called OPUS (acronym for Out of Plane Ultrasonic System).  Now SoniSys has developed a unique 3-dimensional ultrasonic test instrument based on a prototype developed by Dr. Brodeur.  Using the OPUS platform, which includes a touch screen interface, this OPUS 3-D instrument will provide similar data in all three dimensions along with Polar or Stiffness orientation diagrams. 

In addition to traditional paper products like liner boards, other paper products have been tested with great success.  Impregnated papers, for instance, can be tracked throughout their multi-stage process because the samples are never destroyed by ultrasonic testing.   Tissue softness testing has produced very promising results using OPUS and some of our customers are using OPUS to look for variations in the stiffness of early- and late-wood samples.   OPUS 3-D is becoming a valuable test instrument in other fields, such as the non-woven and plastic industry, because of its’ unique ability to test a wide range of materials non-destructively.

SoniSys is committed to helping your company use ultrasonic testing to develop meaningful quality and process control methods to reduce your company’s cost and maintain your desired product quality.   For more information please call Bill Sandidge at 404-352-9421.
