Abstract:
A mirror assembly of micron dimensions for use in deflecting a beam of light comprising a planar base, a planar mirror spaced apart from the planar base and disposed generally parallel to the planar base, the planar mirror having first and second end portions and a longitudinal axis extending between the first and second end portions, first and second torsional members extending along the longitudinal axis and connected to the respective first and second end portions for permitting the mirror to rock between first and second positions about the longitudinal axis relative to the planar base, means for securing the first and second torsional members to the planar base, at least a portion of the mirror being of a conductive material, first and second spaced-apart electrodes carried by the planar base for driving the mirror between the first and second positions, a tether member extending transversely of the longitudinal axis and being secured to the first torsional member and means for securing the tether member to the planar base whereby the tether member regulates the rocking of the mirror.
