The MIF consists of PRC, BS, Arm cavities and SRC. OMC is at the interface between the MIF and the Output Optics group. This working group's task is to set the optical parameters of the MIF (except for the ones set by the detector configuration group) and design the sensing and control scheme for the length and alignment. We are also responsible for maintaining the detailed optical layout.
