Abstract:
1. A multi-channel fiber optic rotary joint mechanism for optic signal transmissions comprising: a first cylindrical-shaped holder with a central hole; a second cylindrical-shaped holder with a central hole; and a third cylindrical-shaped holder with a central hole; said first holder, said second holder and said third holder defining a common axis; said first holder and said second holder being rotatable relative to said third holder around said common axis; a first fiber optic collimator bundles disposed in the central hole of said first holder; a second fiber optic collimator bundles disposed in the central hole of said third holder; and an optic de-rotating element positioned in the central hole of said second holder between said first fiber optic collimator bundle and second fiber optic collimator bundle; an internal gear mechanism with an anti-backlash flexure, means for providing rotation for said second holder at an rotational rate half the rotational rate of said first holder relative to said third holder.
