Abstract: A dome protects an articulating gimbal that orients a line-of-sight of a laser beam. The dome is mounted on a host and encloses the articulating gimbal. The dome has first and second shells. The first shell is rotatable about a first axis relative to the host, and the second shell is disposed on the first shell and is rotatable about a second axis relative to the first shell. A first actuator is coupled to the first shell and is configured to rotate the first shell about the first axis relative to the host. A second actuator is coupled to the second shell and is configured to rotate the second shell about the second axis relative to the first shell. A controller is coupled to the first and second actuators and is configured to match the rotation of the first and second shells to the line-of-sight of the laser beam.
