An acoustooptic spectrum analyzer is described that is based on a new method of measuring spatial light intensity distribution in the Fourier plane. Instead of a detector array, an acoustooptic Bragg cell combined with a fast high dynamic range detector is used. With special driving signals, a time—bandwidth product of >1000, a speed of <50 μs/spectrum, and an increased dynamic range of >40 dB can be achieved.
