    • A system and method of calibrating a laser tracker is provided. The system includes a support system for quickly and easily moving an artifact to a desired position and orientation and for holding the artifact in the position and orientation. An adjustable alignment mirror is coupled to a first end of the artifact so that the more accurate ranging system of the laser tracker can be isolated to determine a reference length of the artifact. Additional measurements are then taken to exercise one or more error source within the tracker. The support system includes a positioner and a support beam for positioning and supporting the artifact. The artifact is coupled to the support beam using kinematic clamps that are designed to reduce or eliminate errors associated with over-constraining the artifact.
    • 提供了一种校准激光跟踪器的系统和方法。 该系统包括用于快速且容易地将伪像移动到期望位置和取向并用于将伪影保持在位置和方向的支撑系统。 可调整的对准反射镜耦合到伪影的第一端,使得可以隔离激光跟踪器的更准确的测距系统以确定伪影的参考长度。 然后进行附加测量,以在跟踪器内运行一个或多个错误源。 支撑系统包括定位器和用于定位和支撑假象的支撑梁。 使用设计用于减少或消除与过度约束伪像相关的错误的运动夹具将该假象耦合到支撑梁。
