Abstract: |
We describe a unique 350 μm beam combiner designed for use on the Large Binocular Telescope (LBT) on Mt. Graham that can be used with either coherent or incoherent detectors. The LBT consists of two 8.4m optical quality primary mirrors on a common azimuth-elevation mount with a centerto- center distance between the primaries of 14.4m, allowing angular resolution of 2″ × 6″ at 350 μm. Unlike the case of traditional radio interferometers, here the beams are combined quasi-optically without the need for a digital correlator. Therefore, the instantaneous bandwidth is limited only by the capabilities of the detector. |
