A linear sequential array has ______ of piezoelectric material arranged _______ in a _______.

A linear sequential array has ______ of piezoelectric material arranged _______ in a _______.

• A. 120-250 rectangular shaped strips; Side by side; Line
• B. 40-60 circular shaped strips; Stacked; Array
• C. 120-250 rectangular shaped strips; In a row; Line
• D. 200-300 trapezoidal strips; Side by side; Line

Answer: (C)

A linear sequential array is built as a single row of piezoelectric elements, forming a line of active area. The typical construction uses rectangular strips, with a count roughly in the 120–250 range, arranged in a row so the aperture extends along one dimension. This arrangement supports steering and scanning along that line. The other descriptions describe circular or trapezoidal shapes, stacking for thickness, or a two-dimensional array rather than a one-dimensional line, which don’t fit the idea of a linear sequential array.
