Optical Sensors and Electromagnetic Actuators (Room Temperature)
Related subgroups: VIS, VAC, CRY
Contents
Scope
Sensors and Actuators for 6 DoF motions of the intermediate masses of vibration isolation system Type-B. This is the LIGO's OSEM-like subsystem that consists of an optical sensor and an electromagnetic actuator (OSEM).
Operating temperature: here the system is assumed to be utilized at room temperature, not in cryogenic temperature.
