摘要：
A dither mechanism comprises a hub (10) arranged to be fixed to a mounting, and a rim (11) coaxial with the hub and to which the ring laser may be attached. A number of radial spokes (12) interconnect the hub (10) and the rim (11), and each has its point of attachment to the rim (11) recessed into the rim in a radial direction. A pair of pegs (32) is associated with at least one spoke and is arranged for insertion into the recesses (15) between the rim and each side of the spoke (12) so as to vary the effective length of the spoke. Drive means (30) are provided for imparting an oscillatory rotational motion to the rim (11) relative to the hub (10) about the axis of the hub.
