Simulating the LISA optical metrology system
Abstract
The optical metrology system (OMS) of LISA is a key component enabling the pm-precision measurements of the spacecraft separations required to measure gravitational waves in the mHz regime. The specific requirements of the LISA OMS make it unique among laser interferometers in many respects. These unique features require custom simulation tools in order to evaluate different design choices and operational modes. We report here on the development of a Hermite-Gauss based simulation of the LISA OMS, to include length and alignment sensing, which we anticipate will provide useful insight into the design and commissioning phases of the mission.
