Shown above are three arrays A1, A2, and A3. Each array contains a different pattern of five scan elements 11, 12, 13, 14, and 15. Each of the arrays will interlace, which means that as the array is indexed a pitch distance P for a new pass, each element will scan a new path, and none of the elements will overlap the scan path of another element. The pitch distance P is equal to the number of elements in the scanning ray times the width of one scan element track. In other words, in the arrays shown above, since there are five elements, the pitch distance is equal to the width of five scan element tracks.
