Abstract
Guided Wave based Structural Health Monitoring greatly benefits from directional scanning. In contrast with conventional phased array approaches, the novel frequency-based beam steering concept and the associated signal processing presented in this work enable imaging of two-dimensional (2D) areas through the output of a single, dual-channel sensor.
