| Summary: | In recent years, the procedures of photoacoustic sensing and imaging techniques have undergone immense growth in both research and applications. Photoacoustic signal is proven to be capable of improving diagnosis in the target original form without physical or chemical alteration. However, even now, the extremely low energy conversion efficiency from light to sound is one of the significant problems of the research. This causes an inferior signal-to-noise ratio (SNR) of the PA signal in the research. To challenge this problem, a digital filter system was implemented in a SoC-class FPGA to reduce the noise in PA signal in near real-time. |
