SYSTEM AND METHOD FOR TRACKING A REFERENCE LASER

A system and method for maintaining a laser impinging on a laser detector assembly include determining a location of the laser from a rotating laser transmitter impinging on a laser sensor. A current position of the laser sensor along a mast of the laser detector assembly is determined and a new position for the laser sensor along the mast is determined based on the location of the laser impinging on the laser sensor and a current position of the laser sensor. The laser sensor is then moved to the new position. The system and method provide an effectively long working range of the laser detector assembly by moving the laser sensor along the mast of the laser detector assembly. An inertial measurement unit is used to calculate position information in the period between laser strikes. 一种用于保持照射在激光检测器组件上的激光的系统和方法，包括确定来自旋转激光发射器的激光照射在激光传感器上的位置。确定激光传感器沿激光检测器组件的杆的当前位置，并且基于激光照射在激光传感器上的位置和激光传感器的当前位置来确定激光传感器沿杆的新位置。然后将激光传感器移动到新位置。该系统和方法通过沿激光检测器组件的杆移动激光传感器来提供激光检测器组件的有效较长工作范围。惯性测量单元用于计算激光入射之间的时间段中的位置信息。
