A novel photoacoustic microscopy (PAM) structure, based on Haar wavelet patterns, is proposed in this paper. Its main goal is to mitigate the PAM imaging resolution and thus the time of its sampling process without compromising the image quality. Owing to the intrinsic nature of wavelet transform, this structure collects spatial and spectral components simultaneously, and this feature speeds up the sampling process by 33%. The selection of these patterns helps in better control of required conditions, such as multi-resolution imaging, to guarantee adequate image quality in comparison to previous microscopic structures. Simulation results prove the superior quality of the proposed approach (about 47% better peak signal-to-noise ratio) compared to the latest structures in this field, achieving a high-resolution and high-quality image.

基于快速小波的光声显微镜

本文提出了一种基于 Haar 小波模式的新型光声显微镜 (PAM) 结构。它的主要目标是在不影响图像质量的情况下降低 PAM 成像分辨率,从而降低其采样过程的时间。由于小波变换的固有特性,该结构同时收集空间和光谱分量,并且该特征将采样过程加快了 33%。选择这些图案有助于更好地控制所需条件,例如多分辨率成像,以保证与以前的微观结构相比具有足够的图像质量。仿真结果证明,与该领域的最新结构相比,所提出的方法具有卓越的质量(峰值信噪比提高约 47%),实现了高分辨率和高质量的图像。
