An ultrasonic probe deployment device in which an ultrasound-transmitting liquid forms the portion of the ultrasonic wave path in contact with the surface being inspected (i.e., the inspection surface). A seal constrains flow of the liquid, for example preventing the liquid from surging out and flooding the inspection surface. The seal is not rigid and conforms to variations in the shape and unevenness of the inspection surface, thus forming a seal (although possibly a leaky seal) around the liquid. The probe preferably is held in place to produce optimum ultrasonic focus on the area of interest. Use of encoders can facilitate the production of C-scan area maps of the material being inspected.

1. A portable ultrasonic probe deployment device for inspecting material located on an inspection surface, the device comprising: a housing;an ultrasonic probe attached to the housing;a conforming seal attached to a bottom side of the housing and conforming to the inspection surface, the conforming seal forming a seal around the inspection site;a cavity created within the housing and the seal, the cavity extending along a portion of an ultrasonic wave path that includes the inspection site;a permeable membrane attached to the bottom side of the housing between the housing and the seal, the permeable membrane dividing the cavity into a non-contact chamber contained by the housing and a contact chamber contained by the seal;a water supply port connected to the non-contact chamber for supplying water to the non-contact chamber, the permeable membrane permitting flow of water from the non-contact chamber to the contact chamber. 2. The device of claim 1, further comprising: roller guides attached to the housing for facilitating movement along a scan direction transverse to the index direction. 3. The device of claim 1, further comprising: a position encoder attached to the housing, for encoding a position of the device along the scan direction. 4. The device of claim 1, further comprising: one or more vacuum ports extending to the inspection surface for removing excess water from the inspection surface. 5. The device of claim 4, wherein the one or more vacuum ports are disposed proximal to the fore and aft ends of the housing, and not disposed along lateral sides of the housing. 6. The device of claim 1, wherein the conforming seal comprises a passageway, the passageway operationally configured to allow a flow of fluid between the contact chamber and the one or more vacuum ports. 7. The device of claim 1, wherein the ultrasonic probe comprises a near wall ultrasonic probe. 8. The device of claim 2, wherein the roller guides and the conforming seal are operationally configured to have a preload offset, the preload offset providing for a desired amount of compression of the conforming seal. 9. The device of claim 1 wherein the permeable membrane is a membrane constructed of non-porous material with perforations. 10. The device of claim 1 wherein the permeable membrane is a perforated membrane. 11. The device of claim 1 wherein the housing is a translucent housing. 12. The device of claim 1 wherein the conforming seal is a polyurethane foam gasket. 13. The device of claim 1 wherein the conforming seal is a rubber gasket. 14. The device of claim 1 wherein the encoder comprises a two-dimensional position encoder for encoding a position of the device along both the scan and index directions. 15. The device of claim 1 wherein the ultrasonic probe is attached to the housing with an adjustable attachment operatively arranged to allow adjusting a standoff height of the ultrasonic probe from the inspection surface. 16. An ultrasonic probe support assembly for use in inspecting material located on an inspection surface, the support assembly comprising: a housing;an ultrasonic probe attached to the housing;a conforming seal attached to a bottom side of the housing and conforming to the inspection surface, the conforming seal forming a seal around the inspection site;a cavity created within the housing and the seal, the cavity extending along a portion of an ultrasonic wave path that includes the inspection site;a permeable membrane attached to the bottom side of the housing between the housing and the seal, the permeable membrane dividing the cavity into a non-contact chamber contained by the housing and a contact chamber contained by the seal;a water supply port connected to the non-contact chamber for supplying water to the non-contact chamber, the permeable membrane permitting flow of water from the non-contact chamber to the contact chamber. 17. The device of claim 16, further comprising: roller guides attached to the housing for facilitating movement along a scan direction transverse to the index direction. 18. The device of claim 16, further comprising: a position encoder attached to the housing, for encoding a position of the device along the scan direction. 19. The device of claim 16, further comprising: one or more vacuum ports extending to the inspection surface for removing excess water from the inspection surface. 20. The device of claim 19, wherein the one or more vacuum ports are disposed proximal to the fore and aft ends of the housing, and not disposed along lateral sides of the housing. 21. The device of claim 16, wherein the conforming seal comprises a passageway, the passageway operationally configured to allow a flow of fluid between the contact chamber and the one or more vacuum ports. 22. The device of claim 17, wherein the roller guides and the conforming seal are operationally configured to have a preload offset, the preload offset providing for a desired amount of compression of the conforming seal. 23. The device of claim 16, wherein the permeable membrane is a membrane constructed of non-porous material with perforations. 24. The device of claim 16, wherein the permeable membrane is a perforated membrane. 25. The device of claim 16, wherein the housing is a translucent housing. 26. The device of claim 16, wherein the housing is a polycarbonate housing. 27. The device of claim 16, wherein the conforming seal is a polyurethane foam gasket. 28. The device of claim 16, wherein the conforming seal is a rubber gasket. 29. The device of claim 18, wherein the position encoder comprises a two-dimensional position encoder, for encoding a position of the device along both the scan and index directions. 30. The device of claim 16, further comprising an adjustable attachment attached to the housing to allow adjusting a standoff height of an ultrasonic probe from the inspection surface.
