摘要：
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 combinedwith a fast high dynamic range detector is used. With special driving signals, a time—bandwidth product of>1000, a speed of <50 /is/spectrum, and an increased dynamic range of >40 dB can be achieved. © 1990 Optical Society of America.
