title = "A multi-axis interferometer based 6-DoF readout system for the gravitational wave detection",
abstract = "A new optical read-out system based on three groups of L-shape 3-axis interferometer is proposed to measure 6-degrees-of-freedom (6-DoF) of the test mass (TM) in the gravitational wave (GW) detection missions. In this system, the source laser is firstly divided into three parts to detect the displacement of the three perpendicular planes of the TM. To decouple the translations and rotations with respect to the XYZ axis, each part of the laser is further applied as the source of the L-shape 3-axis interferometer for the posture detection of each plane. The results of the numerical simulation showed that the solution accuracy of the translation and rotation are better than ±2×10-2 pm and ±3×10-5 nrad respectively, proving the computational accuracy is sufficient for the project requirements. The works above will provide a theoretical basis of the optical read-out system for the space-based GW detection mission.",
