摘要：

TNO TPD, in close cooperation with Micromega-Dynamics and Dutch Space, has developed an advanced Optical Delay Line (ODL) for use in PRIMA, GENIE and other ground based interferometers. The delay line design is modular and flexible, which makes scaling for other applications a relatively easy task. The developed technology can also be applied in future cryogenic space interferometers, such as DARWIN, and TPF-I. The ODL has a single linear motor actuator for Optical Path Difference (OPD) control, driving a two-mirror cat's eye with SiC mirrors and CFRP structure. Magnetic bearings provide frictionless and wear free operation with zero-hysteresis. The delay line has been assembled and is currently being subjected to a comprehensive test program.
