Optical Lever (Room Temperature)
Related subgroups: VIS, IOO, MIF, VAC, CRY...
Contents
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.

Naming Conventions
TBD
Locations
- BS chamber
- ITM chambers (X,Y)
- ETM chambers (X,Y)
- PRC chambers (dummyPRC, PR2, PR3)
- SRC chambers (dummySRC, SR2, SR3)
- MC chambers (MC1, MC2...)
Requirements
- 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.
