Method of operating a fast scanning mirror

A method of operating an adjustable mirror, which is a magnet forming part of a magnetic circuit, 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 intermediary inner stage,
• first mechanical means for pivotally supporting the intermediary inner stage to rotate about a first rotational axle on a first axis of rotation, said intermediary inner stage being rotatable relative to a base on one or more first frictionally rotational pivot points without developing torsional deformation of the first rotatable axle,
• a reflector,
• second mechanical means for pivotally supporting the reflector from the intermediary inner stage to rotate about a second rotational axle on a second axis of rotation, said reflector being rotatable relative to said intermediary inner stage on one or more second frictionally rotational pivot points without developing torsional deformation of the second rotatable axle, and
• a control system establishing angles of the inner stage and of the reflector, 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 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.
