Patent ID: 8752969

Claim:
A method of operating an adjustable mirror to detect and respond to an incident ray from an external object, and to redirect a radiation beam from a laser source; wherein said adjustable mirror has an associated dual-axis steering device comprising: an inner stage, first mechanical means for pivotally supporting the inner stage about a first rotational axle on a first axis of rotation, said inner stage being rotatable relative to a base on a first frictionally rotational pivot point without developing torsional deformation of the first rotatable axle, a reflector, second mechanical means for pivotally supporting the reflector from the inner stage, about a second rotational axle on a second axis of rotation, said reflector being rotatable relative to said inner stage on a second frictionally rotational pivot point without developing torsional deformation of the second rotatable axle, and a magnetic-circuit control system for controlling an angle of the reflector with respect to a radiation beam from the laser source, and said method comprising the steps of: first, utilizing the dual-axis steering device to measure an incident angle of the incident ray from the external object; and second, utilizing the magnetic-circuit control system of the dual-axis steering device to steer the reflector to direct the radiation beam from the laser source toward the external object in response to the measured incident ray.
