There are difficult problems involved in building a near-IR interferometer which uses more than two elements simultaneously. These problems have been overcome at the Cambridge Optical Aperture Synthesis Telescope (COAST). This has allowed us to make the first closure phase measurements on an astronomical source in the IR. We describe a scheme for fast, low noise readout of an IR focal-plane array detector, capable of adequately sampling pupil plane fringe on three simultaneous baselines, as well as a procedure for aligning a many-component beam-combiner in the IR. Finally, the performance of the working COAST IR system is discussed.
