performance compared to the other existing methods, like butterworth filter, sqtwolog threshold denoising, and so on, with 20%-40% improvement. What’s more, our proposed method is significantly effective in processing the two-layers structure, which exhibits different PA signal’s frequency band. In such situation, our proposed method performs better than the existing de-noising methods. By employing the proposed fast and high-performance de-noising algorithm, it enables the using of a lower power laser to achieve the same SNR, which will decrease the cost of a PA imaging system.
