Acoustic phased source and the formation of acoustic beam───相控声源与声束的形成
For scattering of a bounded acoustic beam from a liquid-solid interface, the principal difficulty comes from the treatment of tie plane wave reflection coefficient.
For the transient spatial response, it is possible to obtain a parallel acoustic beam by eliminating the edge wave, and a long axis focusing beam by eliminating the plane wave.
Compared with traditional ultrasonic probe, ultrasonic phased array probe can realize transition, deflection and dynamic focusing of acoustic beam under electronic control.
The direction of acoustic beam and angular width of main lobe can be changed by properly amplitude-weighting, decreasing the frequency of impulsive signal and adjusting the interval of array elements.
