DMA: Acoustic focusing + electronic focusing

• DMA: Using dual matrix array probes.
• Two Groups: Two groups of elements and different angles to fully cover the whole weld area.
• TR Mode: Support transmit and receive longitudinal waves for better penetration and near-surface resolution.
• Adjustable Focus Area: The diamond-shaped focus area can be adjusted to cover the testing thickness.
• Creeping Wave: Excitation of creeping waves to cover near-surface.
• SNR: The "pseudo-focus effect" produces better focusing effect and signal-to-noise ratio.
