摘要： An ultrasonic matrix phased array inspection system can include a plurality of curved matrix phased array probes surrounding a test chamber through which a longitudinal test object passes. Fluid injectors can provide a rotating fluid jacket around the longitudinal test object to ultrasonically couple the plurality of curved matrix phased array probes to the longitudinal test object. The plurality of curved matrix phased array probes can remain in a fixed position during inspection and can inspect the longitudinal test object by transmitting ultrasonic sound waves at various angles to identify flaws of any orientation.

摘要： Systems and methods are disclosed herein in which multi-level square wave excitation signals are used instead of or in addition to fully-analog excitation signals to drive an array of transceiver elements to create a sound field. Use of multi-level square wave excitation signals produces acceptable transceiver output with reduced complexity, cost, and/or power consumption as compared with use of fully-analog excitation signals. In addition, use of such signals facilitates system implementation using application-specific integrated circuits (ASICs) and is not as restricted in voltage level and speed. At the same time, the benefits and applications of fully-analog excitation signals (e.g., acoustic holography, beam superposition, signal-to-noise ratio (SNR) improvements, suppression of parasitic modes, increased material penetration, potential for coded pulsing algorithms and suppression of side lobes in ultrasonic field) can still be achieved with multi-level square wave excitation signals.

摘要： A method and system for inspecting a rail profile include using ultrasonic phased arrays. Determined anomalies, such as material flaws like volumetric defects and cracks, in a fluid-immersed rail profile are detected by employing one or more phased array probes located proximate the rail profile. Electronic delays and beam steering and focusing can be employed to tailor the inspection to the rail geometry.

摘要： An ultrasonic holography imaging system and method are provided. The ultrasonic holography imaging system includes an ultrasonic transducer array coupled to an analog processing section. The analog processing section is coupled to a digital processing section. The digital processing section generates digital signals to be converted by the analog processing section into analog signals that are transmitted to individual transceiver elements within the ultrasonic transducer array to cause separate ones of the individual transceiver elements to emit ultrasonic waveforms that are differentiated from each other by one or more parameters, including amplitude, frequency, and phase or modulation thereof.

摘要： An inspection system for performing an inspection of an end region of a part is provided. The inspection system includes a robotic assembly positioned along a side of the part. The inspection system includes an ultrasonic probe coupled to the robotic assembly and positioned in proximity to the end region of the part. The ultrasonic probe is moved by the robotic assembly along a path to inspect the end region of the part. During the inspection, the ultrasonic probe transmits a signal towards the end region of the part and receives a reflected signal from the end region of the part. The inspection system provides, as a single system, for inspection of both a body of the part and the end region of the part.
