摘要： An ultrasonic probe includes a probe body having a contact surface and a cavity that is open at the contact surface, an ultrasonic transducer carried by the body, and a spacer within the cavity. The spacer has a first surface acoustically coupled to the transducer, and a second (coupling) surface within the cavity. The spacer propagates an acoustic signal between the transducer and the coupling surface. The coupling surface is spaced apart from the contact surface to form a recess within the body. The body further has at least one port for circulating a coupling fluid into the recess. Depth of the recess is selected to balance gravitational force on the coupling fluid versus surface tension of the coupling fluid so a bead of the fluid forms over an edge of a structure under inspection as the probe is moved over the edge.

摘要： An ultrasonic probe for examining an item. The probe includes a body having a contact surface adapted for contacting the item when being examined and an ultrasonic transducer attached to the body and spaced from the contact surface. The probe further includes a spacer positioned in the body between the transducer and the contact surface for spacing the transducer from the item when being examined. The spacer includes a coupling surface facing the item when being examined and a transducer surface facing the transducer. The probe also includes a fluid outlet positioned adjacent the coupling surface of the spacer for delivering coupling fluid to the coupling surface as a film so that the coupling fluid tends to maintain contact with the spacer due to surface tension after the fluid is delivered through the outlet.

摘要： Methodologies and systems to compare images with different levels of contrast are provided. Contrast is normalized between the images with different contrast levels and brightness is set. When normalizing contrast a derivative of gray level is determined for a first digital image having a first contrast level, and a derivative of gray level is determined for a second digital image having a second contrast level that is greater than the first contrast level. A ratio of the derivative of gray level for the first digital image to the derivative of gray level for the second digital image is determined, and the derivative of gray level for the first digital image is equalized with the derivative of gray level for the second digital image. Brightness of at least one image may be set automatically, such as by calculating an average pixel value excluding background and text, or manually.

摘要： A system and method that allow inspection of hollow structures made of composite material, such as an integrally stiffened wing box of an aircraft. A wing box comprises top and bottom skins connected by a plurality of spaced spars. The system employs a plurality of scanners for inspecting different portions of each spar. The system uses dynamically controlled magnetic coupling to connect an external drive tractor to computer-controlled scanners that carry respective sensors, e.g., linear ultrasonic transducer arrays. A system operator can control the various components by means of a graphical user interface comprising multiple interaction regions that represent the individual scanner motion paths and are associated with respective motion script files.

摘要： System and method for enabling ultrasonic inspection of a variable and irregular shape. The system comprises one or more ultrasonic pulser/receivers, one or more ultrasonic transducer arrays, a shoe or jig to hold and position the array(s), data acquisition software to drive the array(s), and data analysis software to select a respective best return signal for each pixel to be displayed. This system starts with information about the general orientation of the array relative to the part and a general predicted part shape. More specific orientation of the transmitted ultrasound beams relative to the part surface is done electronically by phasing the elements in the array(s) to cover the expected (i.e., predicted) surface as well as the full range of part surface variability.

摘要： Improved apparatus, systems, and methods for inspecting a structure are provided that use a probe having two ultrasonic transducer arrays. This enables simultaneous testing using two different test frequencies. The probe uses pulse echo ultrasonic signals at different frequencies to inspect the structure. The probe includes a support body having a fluid conduit formed therein. The fluid conduit provides flow paths for a couplant (such as water) that is used to couple the ultrasonic signals between the structure under test and the arrays. The fluid conduit is configured to quickly eject couplant and bubbles contained in the couplant.
