Click on the CATALOG button for complete list. Angle beam transducers are designed to be used with a wedge, or integrated wedge, to transmit the ultrasound into the material at an angle. Most sensors use transducers that radiate sound in a conical pattern. A wider, bigger beam angle of sound waves will give you coverage of a larger area to see in an image on your display. Improved methods, systems, and apparatus for inspecting a structure using angle beam shear wave through-transmission ultrasonic signals involves positioning transducers at offset positions on opposing sides of the structure and permits inspection of the inside of the structure beneath surface defects and features. The beam angle of the conical pattern is defined as the total angle encompassing where the sound pressure being radiated has been reduced by 3 dB on both sides of the peak pressure produced directly in front of the transducer. Wedges (sold separately) are used to hold the unit at the desired angle. Each column of F contains fan-beam projection data at one rotation angle. If you do not see what you need, please contact us to discuss your requirements. F = fanbeam (I,D) calculates the fan-beam projection data (sinogram) F from the image I.
