An IOAOSA (Integrated Optical Acoustooptic Spectrum Analyzer) system consists of semiconductor laser, acoustooptic modulator, geodesic lenses, and CCD detector array. The optical signal is converted to electrical signal by CCD array of the IOAOSA processor, and then the signal is processed by the signal processing center which consists of TMS32010 system and IBM-PC. The TMS32010 is used in the microcomputer system. It has very high speed. A cyclic sample method is used to collect the data of the CCD video signal, sampling one point every 40 points. After
processing, the frequency bandwidth. the
resolution and the dynamic range of the system are measured to be 100MHz, 8MHz and 20dB respectively.
