Abstract

The delay lines currently under development for the MRO Interferometer will provide up to 380m of optical delay with only 3 reflections. We describe the novel aspects of the delay line design which include using the inside walls of the vacuum pipes as "rails", active shear compensation, and replacing dragged cables with contactless power transfer and communication. We describe the results of tests of various of these design concepts, and progress on the design and construction of the prototype trolley.
