Scope

Sensing local motions including longitudinal dof and all alignment dofs (pitch, yaw and roll) of any mirrors supported by vibration isolation system.

Operating temperature: here the system is assumed to be utilized at room temperature, not in cryogenic temperature.

TBD

Sensor noise should be less than xxx.
Sensor's dynamic range should be greater than xxx.
At least horizontal degrees of freedom (X,Y)
Preferably a vertical sensor (Z) and side
The sensors have to be rigidly mounted on the ground so that these are useful for remembering the position of the mirror and recording the drifts.
