| Abstract: | Based on digital signal process (DSP), this article gave the design method of an electronic board, which is used in the scanning imaging system of sonoluminescence tomography (SLT). The architecture of the board is of high performance and flexibility. The board can independently provide all the real time functions relevant to the scanning imaging of SLT, including the transmitting of ultrasonic wave, the receiving of optical signals, mechanical driving and location, the controlling of scanning strategy and the processing of tomography, etc. The board also can transfer the data to personal computers based on the serial protocol, to do the post processing research of tomography algorithm. The testing result is satisfactory. |
