This feature gives the Sonoscan acoustic microscope operator the ability to collect and digitally store comprehensive acoustic data on parts under inspection. With this ability a more complete sample analysis is possible, even when the sample is no longer available. Components that are placed into high reliability situations (e.g., satellites, airplanes, missile systems) are often analyzed using this feature to provide a more complete archival documentation of the component for future evaluation.
The main capabilities of VRM include Time Domain Imaging (TDI), Frequency Domain Imaging (FDI), B-scan (cross-sectional) Imaging, ZipSlice/3V Imaging and Profile (depth of feature) Imaging. Each imaging mode provides unique information that combines to yield a more comprehensive analysis of a sample.
From the control screen the operator has access to each of these imaging modes. Once the acoustic data has been stored using VRM, the data can be analyzed by using specialized software on any compatible computer. With this software, each of the imaging modes is generated from the original VRM data and since the data is stored digitally the component may be virtually inspected as many times as desired. This allows for a more complete analysis of the part, archive storage and unlimited refinements of the inspection at a later date.
