| 1. Dual Axis Tilting Arm and Bridge Manual Scanner | |
 |
Functionality: Manual random motion in X and Y directions or lock one axis and linear motion in the other axis. The sensor is attached to a gimbals that is hand held against the surface of the part to be scanned.
Attachment: Rubber suction cup feet and/or tape Companies: Matee/SONIX, Infometrics, Sierra Matrix, Physical Acoustics, Nuson, ABB Amdata, DuPont. |
| 2. Dual Axis Tilting Arm and Bridge Automated Scanner | |
 |
Functionality: Stepping motor control in X and Y directions with one axis as a step axis and the other as a linear fast scan axis. Tilting arm is spring loaded to keep the sensor firmly against the surface to be scanned. The sensor is attached to a gimbals and kept perpendicular to the surface.
Attachment: Three rubber suction cup feet with independent hand vacuum pumps. Companies: DuPont/CalData. |
| 3. Radial Axis Tilting Arm with Rotation Axis Bridge Manual Scanner | |
 |
Functionality: Manual random motion in radial and angular directions, either axis can be locked. The sensor is attached to a hand held gimbals and held firmly against the surface to be scanned. Attachment: Rubber suction cup feet with independent hand or AC vacuum pump. Companies: Krautkramer Branson, Tecrad, Systems Research Laboratories (Tilting arm replaced by articulated arm). |
| 4. Dual Axis Cantilever Arm Bridge Manual or Automated Scanner | |
 |
Functionality: Step in X direction and manual or automated scan in Y direction. Step axis consisting of a carriage holding the rigid Y axis arm cantilevered over the area of interest. X axis guide can be rigid or flexible and of long length. For some designs, sections can be butted together for automated scans of extremely long distances. X axis carriage is attached mechanically to the guide or held in place with magnetic wheels on a steel flexible track. Sensor holder is in a gimbals and spring or hydraulically loaded against the scanning surface. Attachment: Rubber suction cup feet with hand or AC vacuum pump. Companies: SAIC, ABB Amdata, Tecrad. |
| 5. Mobile Automated Ultrasonic Scanner | |
 |
Functionality: Automated oscillating linear motion of multiple sensors in the Y axis and manual to or fro motion in the X axis. Attachment: Scanner carriage is hand held to the surface to be scanned. Companies: McDonnell Douglas. |
| 6. Dual Axis Rectangular Bridge Automated Scanner | |
 |
Functionality: Step or fast motorized motion in X or Y directions. Sensor holder is fixed to motorized Y bridge and spring loaded against the surface to be scanned. Attachment Rubber suction cup feet with AC vacuum pump. Companies: Panametrics, Xactex |
| 7. Hands Free X-Y Digitizer | |
 |
Functionality: X-Y digitizing by acoustic triangulation system or LED Video system. Hands-free random manual motion in X or Y directions. Sensor holder is held in the hand and the high frequency acoustic source or LED is attached to the holder. A pair of microphones attached to a bar is placed in front of the area to be scanned or the video camera is placed above the area to be scanned.
Attachment: Microphones are on a bar that is attached by rubber suction cup feet to the surface to be scanned. Companies: SE Systems, Inc.(acoustic), Sonomatic Inc.(LED) |
| 8. 2-D Square Transducer Array | |
 |
Functionality: Electronic switching between small transducer elements of the 2-D square transducer array arranged in a flexible rubber sheet.
Attachment: Suction to the surface with a vacuum blanket and AC pump. Companies: Failure Analysis Associates. |
