    • A modular omnidirectional laser-based bar code symbol scanning system having at least one scan module insert that is removably disposed (e.g., removably installed) within a system housing (or portion thereof) through a service port (e.g., opening) in the system housing (or portion thereof). The scan module insert is a self-contained unit including at least the following components (in addition to mechanical support structures for such components): at least one laser diode, a rotating scanning element, an electric motor that rotates the rotating scanning element, one or more photodetectors, and analog signal processing circuitry that conditions (e.g., amplifies and/or filters out unwanted noise in) the electrical signal produced by the one or more photodetectors. The scan module insert can optionally include additional components including one or more light collecting , optical elements, one or more beam folding mirrors, circuitry for detecting and decoding bar code symbols scanned by the system, etc. The modular architecture of omnidirectional laser scanner of the present invention enables quick access to the scan module insert for efficient repair/reconfiguration/configuration of the optical components, electro-optical, electro-mechanical components and/or electrical components integral thereto.
    • 一种基于模块化全向激光的条形码符号扫描系统,其具有至少一个扫描模块插件,其通过系统壳体(例如,开口)可移除地设置(例如,可移除地安装)在系统壳体(或其部分)内 (或其部分)。 扫描模块插入件是独立的单元,至少包括以下部件(除了用于这些部件的机械支撑结构之外):至少一个激光二极管,旋转扫描元件,旋转扫描元件的电动机,一个 或更多的光电检测器,以及模拟信号处理电路,其对由一个或多个光电检测器产生的电信号进行条件(例如,放大和/或滤除不需要的噪声)。 扫描模块插件可以可选地包括附加的组件,包括一个或多个聚光,光学元件,一个或多个光束折叠镜,用于检测和解码由系统扫描的条形码符号的电路等。全向激光扫描仪的模块化架构 本发明使得能够快速访问扫描模块插件,用于有效地修复/重新配置/组合光学部件,电光学,机电部件和/或与其成为一体的电子部件。
