A method and apparatus for measuring a structure. An x-ray system and the structure are positioned relative to each other. The x-ray system comprises a gas source configured to provide a gas, a laser system configured to emit a laser beam, a steering system, and a detector. The steering system is configured to direct a first portion of the laser beam into the gas such that an electron beam is generated by the laser beam interacting with the gas and is configured to direct a second portion of the laser beam into the electron beam such that a collimated x-ray beam is formed. The detector is configured to detect the collimated x-ray beam. The collimated x-ray beam is emitted with the structure positioned relative to the x-ray system.

A system for imaging in a structure may include an energy beam source to direct an energy beam at the structure and a detector to detect a backscatter of the energy beam from any object in the structure. The system may also include a time-resolved function to generate an image of any object in the structure using the backscatter of the energy beam.

A system for measuring a mixture ratio associated with a two-part fluid, at least one of the two parts including conductive particles. The system includes a pair of electrodes, a circuit, and an output. The electrodes are disposed on opposite sides of the two-part fluid and sense the dielectric strength of the fluid. The circuit communicates with the electrodes to sense the dielectric strength and outputs a signal representing the dielectric strength. Preferably, the circuit includes a capacitive bridge, an input for a set-point, and an output for an error signal. Also, the system can include a housing for the electrodes. A timer may also be provided to measure the time elapsed from the beginning of the mixing of the two-part fluid. Preferably, the two-part fluid is an adhesive with aluminum particles that is made from a resin and a hardener. Methods of producing two-part fluids are also provided.

A hybrid inspection system and method are provided which utilize both an air-coupled transducer and a liquid-coupled transducer in order to enjoy the advantages offered by both types of transducers. The hybrid inspection system may include a first probe that includes the air-coupled transducer, such as a capacitive machined ultrasonic transducer, which is configured to emit ultrasonic signals and to air couple the ultrasonic signals into a workpiece. The hybrid inspection system may also include a second probe that includes the liquid-coupled transducer, such as a piezoelectric transducer, configured to receive the ultrasonic signals emitted by the air-coupled transducer of the first probe via a liquid coupling between the transducer and the workpiece.

摘要:
A method and apparatus for multi-energy object inspection using a brilliant x-ray source. A first mono-energetic x-ray image of an object at a first selected energy is generated. A second mono-energetic x-ray image of the object at a second selected energy is generated. The first selected energy is different than the second selected energy. Additional mono-energetic x-ray images may be generated at energies different than previous energies up to n selected energies. The mono-energetic x-ray images are mathematically combined and processed to form a result. The result of processing the mono-energetic x-ray images is presented. The result comprises processed mono-energetic x-ray image data describing materials in the object with greater sensitivity, identifying the layers, and identifying the material composition than in the first image or the second image.
摘要:
A method and apparatus are provided to identify unacceptable levels of porosity, microcracking or defects attributable to thermal damage. Ultrasonic signals are introduced into the workpiece, such as by means of an ultrasonic transmitter. The ultrasonic signals propagate along a predefined axis of propagation oriented at an offset angle relative to a predefined reference direction oriented normal to the workpiece. Backscattered signals are received, such as by an ultrasonic receiver, from the workpiece. A measure representative of the cumulative energy of the backscattered signals received over a predefined time interval is then determined, such as integration performed by a processing element. An anomalous response may then be detected based upon the measure representative of the cumulative energy of the backscattered signals. This anomalous response may be representative of at least a predefined amount of porosity, microcracking or thermal damage.
