1 High Resolution, Low Cost Ultrasound Camera for In-service Composite NDI Robert Lasser, Marvin Lasser, Ron Westernik, John Kula, David Rich Imperium, Inc.

2 Imperium Formed in 1996 Focused solely on ultrasound camera technology In development for 10 years, now selling commercially Implement for different embodiments of ultrasound camera

3 Medical Image of Finger: Easy-to-Interpret Image Examples Industrial Detection of Fault: Imperium Conventional Defect Bone

4 Industry Sectors Industrial Industrial Underwater Underwater Biometrics Biometrics Medical Medical

5 Sampling of Customers

6 Imperium Architecture Apply optical imaging techniques to ultrasound Optical Sensor Lens

7 Imperium Architecture Ultrasound Sensor Acoustic Lens Set Acoustic Flashlight

8 Through Transmission Source TransducerTargetAcoustic LensImaging Array

9 Piezoelectric Layer Pre-amp/ detection Signal Conditioning Multiplexing Pin Grid Array Package Ultrasound (piezoelectric) material Read out integrated circuit (ROIC) Wire bonds I500 to I600

10 Through Transmission of Composite Laminate Three inches

11 SoundTransmitter Array Electronics Video Water Water Lens Lens Target Subsurface fault DAV TM Technology - Pulse Echo Pulse echo image of quarter

12 SoundTransmitter Array Video Lens Lens Target Subsurface fault Pulse Echo – 50/50 Beamsplitter Pulse echo image of quarter Acoustic beamsplitter Water Water

13 Pulse Echo of Composite Laminate One inch

14 Pulse Echo of Quarter One inch

15 Beamsplitter Source transducer Target Imaging Array LCD Acoustic Lens Camera Head Cutaway

16 B-scan versus C-scan Defect

17 Impact Damage in Composite Structure Leading Edge Inspection One inch

18 Pulse Echo of Honeycomb Composite One inch

19 Range Gating Gate 1 Gate 2 Gate 3

20 Range Gating for Depth: Pick the C-scan plane of interest

21 Transparent A-scan Sensor Integrated A-scan for Flaw Detector Functionality

22 Presentation of Imagery and A-scan/ Match Gates Set A-scan gates, automatically changes C-scan gates

23 Production Scanning Results: ATK Thiokol Graphite/epoxy laminate defect standard with embedded Teflon wafers Hex nut and paper clip placed on surface

24 UT camera scan with stitching algorithm applied scan increment Conventional immersion scan MHz, 0.25 diameter transducer scan increment

25 Gridlines/Sizing

26 Future Developments: Pulse Echo Handheld portion goes from 4 lbs. to 2 lbs.

27 Current Development: Camcorder Handheld Handheld portion goes from 4 lbs. to under 2 lbs. Focus with finger Strap Grip

28 New Control Unit

29 Current Development: Camcorder Handheld

30 Time of flight: color code different depths Increments to be selected by user (e.g. 1 mm) Blue: Level 1 Red: Level 2 Yellow:Level 3

31 Future Developments: Through Transmission

32 Lack of trained NDI personnel Lack of trained NDI personnel Use by non-certified personnel Use by non-certified personnel SIMPLE, SIMPLE, SIMPLE SIMPLE, SIMPLE, SIMPLE Remotely monitored in real time Remotely monitored in real time Wireless Wireless Program began in early 2007 Program began in early 2007 Boeing Remote NDI Program

33 Remote Wireless NDI Program C-scan, A-scan, Audio, Video of inspection Audio, Control of camera
