We excited this research pro'ect for 2 years and got the following results.1. The ring typed traiisdlicer array with 8 elements was developed to generate the spherical wave pulse and receive the echo signal from 3-dimensional field.2. The high speed data acquisition system was developed to digitalize each output signal with 40 Hz and 8 bits using the liigli speed AD converter and RAM chips.3. The image processor with 1-chip DSP was developed to process the time-fright method. The ability of this was 20 MIPS.4. The imaging algorithm was developed for visualing the 3-dimensional scene. And also, the one for the stereo image was developed.5. The 3-dimensional image was got in the basic experiment using the water vessel.

我们对这个课题进行了两年的研究，取得了以下成果： 1．研制了8元环型跟踪器阵列，用于产生球面波脉冲并接收来自3维场的回波信号。 2．开发了高速数据采集系统，使用liigli高速AD转换器和RAM芯片将每个输出信号数字化为40 Hz和8位。 3．开发了带有单片DSP的图像处理器来处理时间恐惧方法。其能力为 20 MIPS.4。成像算法是为了可视化 3 维场景而开发的。并开发了立体图像的系统。 5． 3维图像是在使用水容器的基础实验中获得的。
