SAFT - Synthetic Aperture Focusing Technique
The animation illustrates a simplified measurement using a MIRA ultrasonic array. It reconstructs the anomalies and backside details from the Ascans. The reconstruction relies on the principle that a signal measured at a specific time must originate from a position given by an ellipse. The ellipise' focal points align with the positions of transmitter and receiver and the radius is represented by the signal transit time.
