The scan plane in a mechanical transducer is created through which mechanism?

• A. Electronic Steering
• B. Digital Steering
• C. Phased Steering
• D. Mechanical Steering

Answer: (D)

In a mechanical transducer, the scan plane is produced by physically moving the transducer’s aperture. A motor or cam shifts the crystal so the emitted beam is directed at different angles as the device scans, sweeping across the image to form the plane. This is different from electronic steering, where timing delays across an array steer the beam without moving the transducer; here the scanning comes from the mechanical motion of the element itself.
