Introduction
We can extract optical beams from the interferometer inside the vacuum chamber at the viewports. The optical beams are for length control scheme of the interferometer, alignment control scheme of the mirrors, optical levers for LCGT-SUS, and other monitoring devices (CCD or equivalent video cameras).
