Abstract
Embodiments include a dither system comprising a support member to support a sensor housing having a common line-of-sight (LOS). A first metal bellows is coupled to the support member and being concentric to the sensor housing to constrain rotational motion of the sensor housing and allow angular motion. An eccentric cam comprising: an outer circumference having an axis coaxial with an axis of the first bellows and an inner circumference including an axis laterally offset from the axis of the first bellow. The eccentric cam drives tilt motion of the sensor housing and LOS. A second metal bellows is coaxial to the inner circumference of the eccentric cam and being concentric to the sensor housing. A position measurement system coupled to the sensor housing tracks the tilt motion of the sensor housing with respect to the angular motion of the eccentric cam. A system and method are also provided.
