High Resolution, Low Cost Ultrasound Camera for In-service Composite NDI Robert Lasser, Marvin Lasser, Ron Westernik, John Kula, David Rich Imperium, Inc. Imperium Composite NDI
  • Formed in 1996
  • Focused solely on ultrasound camera technology
  • In development for 10 years, now selling commercially
  • Implement for different embodiments of ultrasound camera
  • Easy-to-Interpret Image Examples Composite NDI Imperium Conventional Bone Medical Image of Finger: Industrial Detection of Fault: Defect Industry Sectors Composite NDI
  • Industrial
  • Underwater
  • Biometrics
  • Medical
  • Sampling of Customers Composite NDI Imperium Architecture Composite NDI Apply optical imaging techniques to ultrasound Optical Sensor Lens Imperium Architecture Composite NDI Acoustic Flashlight Ultrasound Sensor Acoustic Lens Set Through Transmission Composite NDI Imaging Array Acoustic Lens Target Source Transducer Ultrasound Composite NDI ( piezoelectric) Read out material integrated circuit (ROIC) Pin Grid Array Package Wire bonds Imaging Array Multiplexing Piezoelectric Layer Signal Conditioning Pre-amp/ detection I500 to I600 Through Transmission of Composite Laminate Composite NDI Three inches Pulse Echo – 50/50 Beamsplitter Composite NDI Sound Transmitter Pulse echo image of quarter Array Subsurface fault Video Water Lens Acoustic beamsplitter Target Pulse Echo of Composite Laminate Composite NDI One inch Pulse Echo of Quarter Composite NDI One inch Camera Head Cutaway Composite NDI Source transducer Imaging Array Target LCD Acoustic Lens Beamsplitter B-scan versus C-scan Composite NDI Defect Defect Impact Damage in Composite Structure Composite NDI One inch Leading Edge Inspection Pulse Echo of Honeycomb Composite Composite NDI One inch Range Gating Composite NDI Gate 1 Gate 2 Gate 3 Range Gating for Depth: Composite NDIPick the C-scan plane of interest “Transparent” A-scan Sensor Composite NDI Integrated A-scan for Flaw Detector Functionality Presentation of Imagery and A-scan/ Match Gates Composite NDI Set A-scan gates, automatically changes C-scan gates Production Scanning Results: ATK Thiokol Composite NDI Hex nut and paper clip placed on surface Graphite/epoxy laminate defect standard with embedded Teflon wafers UT camera scan with stitching Composite NDI algorithm applied - 0.3” scan increment Conventional immersion scan - 2.25 MHz, 0.25” diameter transducer - 0.075 scan increment Gridlines/Sizing Composite NDI Future Developments: Pulse Echo Composite NDI Handheld portion goes from 4 lbs. to 2 lbs. Current Development: Composite NDI‘Camcorder’ Handheld Focus with finger Strap Grip Handheld portion goes from 4 lbs. to under 2 lbs. New Control Unit Composite NDI Current Development: Composite NDI‘Camcorder’ Handheld Time of flight: color code different depths Composite NDI Blue: Level 1 Red: Level 2 Yellow: Level 3 2 3 3 1 2 Increments to be selected by user (e.g. 1 mm) Future Developments: Through Transmission Composite NDI Boeing Remote NDI Program Composite NDI
  • Lack of trained NDI personnel
  • Use by non-certified personnel
  • SIMPLE, SIMPLE, SIMPLE
  • Remotely monitored in real time
  • Wireless
  • Program began in early 2007
  • Remote Wireless NDI Program Composite NDI C-scan, A-scan, Audio, Video of inspection Audio, Control of camera Boeing Remote NDI Program Composite NDI
  • Successful demonstration Fall 2008
  • Equipment at Boeing’s Everett, WA production facility
  • Remotely monitored at Boeing’ GoldCare center in Seattle, WA
  • Pilot program with airlines during 2009
