    • A bioptical laser scanning system employing a plurality of laser scanning stations about a two independently controlled rotating polygonal mirrors. The system has an ultra-compact construction, ideally suited for space-constrained retail scanning environments, and generates a 3-D omnidirectional laser scanning pattern between the bottom and side-scanning windows during system operation. The laser scanning pattern of the present invention comprises a complex of quasi-orthogonal laser scanning planes, including a plurality of substantially-vertical laser scanning planes for reading bar code symbols having bar code elements (i.e. ladder type bar code symbols) that are oriented substantially horizontal with respect to the bottom-scanning window, and a plurality of substantially-horizontal laser scanning planes for reading bar code symbols having bar code elements (i.e. picket-fence type bar code symbols) that are oriented substantially vertical with respect to the bottom-scanning window.
    • 一种采用多个激光扫描站的生物激光扫描系统,可以围绕两个独立控制的旋转多面镜。 该系统具有超紧凑的结构,非常适合空间受限的零售扫描环境,并在系统操作期间在底部和侧面扫描窗口之间生成3-D全向激光扫描图案。 本发明的激光扫描图案包括准正交激光扫描平面的复合体,其包括多个基本上垂直的激光扫描平面,用于读取具有基本上定向的条形码元素(即,梯形条形码符号)的条形码符号 水平方向相对于底部扫描窗口,以及多个基本上水平的激光扫描平面,用于读取具有相对于底部扫描窗口大致垂直取向的条形码元素(即,栅栏栅栏型条形码符号)的条形码符号, 扫描窗口。
