1. A method for using a multi-axis motor, the method comprising:
adjusting a first axis of a first motor by moving a first magnet member in a first coil, wherein:
the first magnet member is coupled with a support structure;
an optical device is coupled with the support structure;
the first magnet member is an elongate magnet member having a length and a width;
the length of the first magnet member is greater than the width of the first magnet member; and
the first magnet member is curved along the length of the first magnet member;
adjusting a second axis of the first motor by moving a second magnet member in a second coil, wherein:
the second magnet member is coupled with the support structure;
the second magnet member is an elongate magnet member having a length and a width;
the length of the second magnet member is greater than the width of the second magnet member;
the second magnet member is curved along the length of the second magnet member; and
the first magnet member and the second magnet member protrude from the support structure at right angles so that the length of the first magnet member is orthogonal to the length of the second magnet member at the support structure; and
adjusting a first axis and a second axis of a second motor, wherein the second motor is for coarse adjustment and the first motor is for fine adjustment of the optical device.
