A targeting and tracking apparatus and method for optical transceivers is
disclosed. The tracking function is performed internally by way of
translating an internal optical fiber in the focal plane of the
transceiver telescope using miniature motorized translation systems
and/or micro-electro-mechanical systems (MEMS). The optical design of the
transceiver provides a wide field of view and a pointing and tracking
field of regard that is directly proportional to the translation of the
optical fiber in the focal plane of the telescope. The apparatus and
method can eliminate the need for external gimballing systems and
scanning mirrors, and replace the gimballed optical beam steering
function with motorized translation systems and/or MEMS that consumes
very little power.
