Research Abstract

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.
