Paper Abstract

We present four alternative designs for a near-infrared science beam combiner for the Magdalena Ridge Observatory Interferometer. The candidate designs considered are: (1) a four way pupil-plane combiner, fed by a "fast switchyard" that would be reconfigured at a few minute intervals to select different subsets of six input beams; (2) a four way image-plane combiner, fed by a similar fast switchyard; (3) an eight way pupil plane combiner; and (4) a six way image plane combiner. The criteria by which fully-optimised versions of the designs will be compared include: realistic signal-to-noise and imaging speed, stability and ease of alignment and calibration, cost (including detector costs), and technical and schedule risk to the MROI project.
