A modular easily transportable acoustooptical spectrometer (AOS) designed for airborne submillimeter astronomical observations is described. The large bandwidth (992 MHz) of the AOS, combined with high resolution (1.7 MHz), make it possible to observe astronomical transitions within a wide variety of spectral widths. The AOS provides its own data acquisition and handling system, enabling on-line data reduction and a high degree of flexibility. The AOS was flown aboard the Kuiper Airborne Observatory in September 1988. Even in the noisy, shaky, and thermally unstable environment encountered by the AOS its performance was comparable to that in the laboratory. A diagram of the electrooptical part of the AOS is included.
