The linear sequential array produces rectangular images.

The linear sequential array produces rectangular images.

• A. Circular images
• B. Rectangular images
• C. Square images
• D. Triangular images

Answer: (B)

A linear sequential array is a one-dimensional set of sensors that captures one line of the image at a time. To form a complete picture, that line is scanned across the scene (or the object is moved), and each successive line is recorded. When you stack these lines, you get a two-dimensional grid of pixels arranged in rows and columns, which produces a rectangular image. The shape isn’t circular, square, or triangular because the sensor’s geometry and the way lines are collected inherently build up width from the line length and height from the number of lines captured, yielding a rectangle.
