Olympus introduces the RollerFORM

Olympus announces the introduction of the RollerFORM, a new ultrasound phased array wheel probe that has been specifically developed to facilitate high-quality, immersion-like ultrasonic testing of composites and other smooth-surfaced materials that are commonly used in the aerospace industry.

An affordable and easy-to-implement replacement for full 2-D encoding systems, the RollerFORM also offers a viable alternative to immersion techniques.

The RollerFORM’s wheel tire is made from a unique material that closely matches the acoustic impedance of water. This design feature permits the efficient transmission of energy to the part without unwanted echoes, obtaining an optimum 1 mm near-surface resolution in composites when using the 5 MHz phased array probe model. The 3.5 MHz probe model is better suited for thicker and more attenuating materials. Since the tire material is transparent, the inspector can easily identify the presence of air bubbles or contaminants within the water chamber. Minimal pressure is required to achieve excellent coupling, ensuring a strong signal even in difficult scanning positions.
