A microcomputer based data acquisition system has been developed for astronomical observing with two-dimensional infrared detector arrays operating at high pixel rates. The system is based on a 16-bit 8086/8087 microcomputer operating at 10 MHz. Data rates of up to 560,000 pixels/sec from arrays of up to 4096 elements are supported using the microcomputer system alone. A hardware co-adder the authors are developing permits data accumulation at rates of up to 1.67 million pixels/sec in both staring and chopped data acquisition modes. The system has been used for direct imaging and for data acquisition in a Fabry-Perot Spectrometer developed by NRL. The hardware is operated using interactive software which supports the several available modes of data acquisition, and permits data display and reduction during observing sessions.
