多面镜校准系统
摘要：
本发明是关于一种光学系统，包含：多个选择性引导面镜(38)，分别被设置用以引导激光束(41)至场域内的可选择的位置；多个面镜方位传感器(45)，用以感测所述多个选择性引导面镜的方位并提供多个面镜方位输出；以及自动校准子系统(47)，用以自动校准所述多个选择性引导面镜，所述自动校准子系统包含：标靶(40)，被用以在所述标靶上提供由激光束照射的光学可见指示，所述标靶是可复写的(rewritable)并具有多个光学可见的基准标记(fiducial marking)(54，56)；标靶定位器(42)，用以选择性定位所述标靶；光学传感器(44)，用以在所述激光束照射在所述标靶上之后查看所述标靶并提供多个激光束照射输出；以及相关器(correlator)(36)，用以提供校准输出。
摘要（英）：

An optical system including a plurality of selectably directable mirrors (38) each arranged to direct a laser beam (41) to a selectable location within a field, a plurality of mirror orientation sensors (45) operative to sense the orientation of the plurality of selectably directable mirrors and to provide mirror orientation outputs and an automatic calibration subsystem (47) for automatically calibrating the plurality of selectably directable mirrors, the automatic calibration subsystem including a target (40) being operative to provide an optically visible indication of impingement of a laser beam thereon; the target being rewritable and having optically visible fiducial markings (54, 56), a target positioner (42) for selectably positioning the target, an optical sensor (44) operative to view the target following impingement of the laser beam thereon and to provide laser beam impingement outputs and a correlator (36) operative to provide a calibration output.
