LCGT Auxiliary Optics Subsystem (AOS)

Objectives
The objectives of the subgroup "Auxiliary Optics System" (AOS) is to have the other LCGT subgroups design and complete the auxiliary optics that physically, logically and consistently glue the main parts of the LCGT interferometer together.
General Description
All the AOS shall be fit to the vacuum chambers that had been already determined when the AOS group was established. Even if the vacuum chamber was not designed considering the space allocated for AOS, AOS are required for fully operating LCGT, so we shall, by any means, pack them into the vacuum chambers if required.

Subsystems
Including beam baffles, output Faraday isolators, and calculation of BRDF of test masses...
- Auxiliary laser-locking system itself should be considered in MIF or IOO. The effort of system designing should be separated from that of engineering and fabricating from the WBS point of view (or what-you-call system engineering) even if the person assigned to both is the same.
- Optical lever is a kind of local sensors, but unlike other local sensors, it requires long beam lines as lever's arms, thus this should be considerd in AOS.
- Other local sensors/monitors/actuators?
- Any other optics, outside breadboard,...
- Squeezing system??
- Maybe mainly VIS group's charge and not AOS's:
