Near Field Calculation and Beam Divergence
Near field calculation and beam divergence are well known for conventional transducers. For a phased array probe, we need to treat the active and the passive axes separately. The [...]
Surface-adaptive ultrasound (SAUL) for Phased Array inspection of composite specimens with curved edges and complex geometry
Please note: this paper is available for download on our PDF downloads page as well. D. L. Hopkins1, M. Brassard2, G. A. Neau1,4, Jean-Noel Noiret3, W. V. Johnson1 and [...]
Effect of Rough Surfaces
The condition of the surface through which a sound beam enters a material affects ultrasonic measurements. Increased roughness reduces the transmitted energy of the sound beam and this, in [...]
Digitization
A digitizer converts the echo waveforms returned by the ultrasonic transducer into digital information using an ADC. For applications that require well-shaped waveforms in the time-domain, a sample rate 10 [...]
Reflector Plate Inspection
Ultrasonic inspection of certain composite materials can be difficult. In fact, highly dense composite materials produce noisy ultrasonic response to pulse-echo inspections. Also, through transmission techniques cannot always be [...]
Side Lobes and Grating Lobees
Since Phased arrays have discrete elements, equally spaced, they can experienced side and grating lobes. They are experienced when the element spacing is greater than a half wavelength (see [...]
Material Velocities/Wavelength/Attenuation
The following table can be used as a quick reference for the wavelength, speed of sound of most commonly used material. Some useful definition includes: Near Surface Resolution: Minimum distance [...]

Porosities – Ultrasonic
Porosity is a known detrimental material condition that includes a plurality of voids in the composite material caused by trapped or evolved gases which may be caused by improper processing, [...]
Sensitivity and Resolution
Sensitivity is the ability of an ultrasonic system to detect defects at a given depth in a test material. The greater the signal that is received from these reflectors, the [...]
Ultrasonic Data Displays
Ultrasonic data can be collected and displayed in a number of different formats. A scan can be shown as an RF, half waves (positive or negative) or a rectified signal. [...]
