Automatic repositioning of mirrors mounted within concave-shaped boundaries

An automatic mirror repositioning system having at least one mirror mounted within mirror movement boundaries, there being an origin at the center of mirror movement, comprising:

• a first motor, connected to the mirror, controlling mirror movement along a first axis;
• a second motor, connected to the mirror, controlling mirror movement along a second axis;
• a first position means, responsive to the position of the mirror along said first axis, for providing a first feedback signal indicative of a current position of the mirror along said first axis;
• a second position means, responsive to the position of the mirror along said second axis, for providing a second feedback signal indicative of a current position of the mirror along said second axis;
• and
• signal processing means, responsive to said first and said second feedback signals, for providing signals indicative of a predetermined target position of the mirror and a predetermined safe region along each axis, for causing said first motor to drive the mirror toward said predetermined target position, said first axis having a distance to the target not less than the distance along said second axis, and for causing said second motor to drive the mirror toward the origin along said second axis until either the mirror position along said second axis is within said predetermined safe region along said second axis or the distances to said predetermined target position along both said first axis and said second axis are substantially equal, then causing said second motor to drive the mirror toward said predetermined target position when the distance to said predetermined target position along said second axis is not less than the distance to said predetermined target position along said first axis.
