BILLERICA, MA-The 3-D Phase Measurement is a game changing measurement technique that provides 3 dimensional imaging to increase accuracy and productivity in aerospace and rotating equipment applications. Paired with the world class XLG3 Video Borescope, this new technology provides accurate 3 dimensional surface scans using a single probe tip. In effect, the 3-D Phase Measurement provides accurate measurement "on-demand" by eliminating the need to change the probe tip to capture the measurement, streamlining the inspection process.

“3-D Phase Measurement gives our customers a more efficient and accurate view of the inspection subject,” said Ed Hubben, senior product manager for the Inspection Technologies product line. “Unlike current techniques, 3-D Phase Measurement does not require a change from a viewing tip to a measurement tip during inspection so it speeds up the entire inspection process.”

Prior to 3-D Phase Measurement, videoprobe measurement was based on stereo or shadow techniques, which are complex techniques, and the tip of the probe had to be changed from a viewing tip to a measurement tip, adding time to the inspection process. 3-D Phase Measurement offers profile views, a cross section view of a portion of the surface. With profile view, the inspector can rotate and zoom to get a more accurate view of the defect. The ability to better visualize the shape and characteristics of an indication allows for well-informed decision of serviceability of the asset.
