The state of the art of the Cologne Acousto Optical Spectrometer (AOS) development for radio
astronomical purposes is presented. A summary of the important features of AOS in general is
given. Two AOS projects are presented, a broadband spaceborne AOS for the Submillimeter Wave
Astronomy Satellite (SWAS) and an AOS with variable resolution for the Kosma 3 m radiotelescope
to be placed on the Gornergrat in Switzerland.
