    • A bi-directional portable laser light detection device for receiving and detecting laser light from one or more of a plurality of sources includes a laser light pipe that comprises a solid body of material that has a high index of refraction and has an input end, an output end, and at least one wall member connecting the input end and the output end. A generally planar laser light admitting zone on the exterior of the solid body at the input end thereof is oriented so as to generally face the expected direction of the path of laser light from a source along a first opposed path so that, in use, the laser light enters the solid body by way of the admitting zone so as to become admitted laser light. A generally planar laser light emitting zone on the exterior of the solid body at the output end thereof is oriented so as to generally face outwardly toward a laser light sensor such that laser light emitted from the laser light emitting zone is received by a laser light sensor. The external periphery of the solid body is shaped and dimensioned so as to transmit and internally reflect the admitted laser light to the laser light emitting zone. The laser light sensor is oriented so as to receive laser light emitted from the laser light emitting zone of the laser light pipe, and also so as to receive laser light along a second opposed path.
    • 一种用于从多个源中的一个或多个源接收和检测激光的双向便携式激光检测装置包括:激光管,其包括具有高折射率并具有输入端的材料的固体, 输出端和连接输入端和输出端的至少一个壁构件。 在其输入端处的固体的外部上的大致平面的激光入射区域被定向成大致面对沿着第一相对路径的来自源的激光路径的预期方向,使得在使用中, 激光通过入口区域进入固体,以便成为允许的激光。 在其输出端处的固体的外部上的大致平面的激光发射区被定向成大体朝向激光传感器朝外,使得从激光发射区发射的激光由激光传感器 。 固体的外周形状和尺寸设计成将入射的激光透射并内反射到激光发射区。 激光传感器被定向为接收从激光管的激光发射区发射的激光,并且还沿着第二相对路径接收激光。
