Summary
[edit]DescriptionPhased array beam.jpg | Principle of operation of phased array (PA). The PA probe consists of many small elements, each of which can be pulsed separately. In this figure the element on the right is pulsed first, and emits a pressure wave that spreads out like a ripple on a pond (largest semi-circle). The second to right element is pulsed next, and emits a ripple that is slightly smaller than the first because it was started later. The process continues down the line until all the elements have been pulsed. The multiple waves add up to one single wave front travelling at a set angle. In other words, the beam angle can be set just by programming the pulse timings. |
