    摘要: A folded retro-reflective optical scanner using common major optics for both scanning and reading and achieving a long scan line (8.25 inches) with a short throw distance and little bow. Astigmatic effects in the reading beam are minimized by utilizing only the center portion of the return beam for reading.
