Patent ID: 6980712

Claim:
An apparatus, comprising: an optical switch having: a first mirror to receive a first light beam and to reflect the first light beam to a predetermined position on a first position sensing detector; a second mirror to receive a second light beam and to reflect the second light beam to a predetermined position on a second position sensing detector, wherein the first and the second position sensing detectors are arranged as a substantially planar array; a control system to control a first orientation of the first mirror, the first mirror to reflect the first light beam to a predetermined position on a first position sensing detector in response to the orientation, the first mirror to receive a third light beam and to direct the third light beam received from a first port to the second mirror in response to the first orientation, the control system to control a second orientation of the second mirror, the second mirror to reflect the second light beam to a predetermined position on a second position sensing detector in response to the second orientation, the second mirror to direct the third light beam to a second port to the second mirror in response to the second orientation, the first and the second orientations to maximize an intensity of the third light beam coupled into the second port, the control system to record signals output from the first and second position sensing detectors; and an aperture plate substantially parallel to and spaced apart from said array by about 0.5 to 1.0 millimeters.
