Abstract

Edge detection is critical for emerging image processing technologies. Here, we present a dual-channel optical differential system that faithfully retrieves full edges of two-dimensional (2D) images. The system, leveraging the modified Wollaston prism, is compatible with hyperspectral imaging (HSI), enabling real-time phase imaging across 450-750 nm with 30 spectral channels. Experimental results demonstrate that the peak signal-to-noise ratio (PSNR) of the image is improved over 6 dB with the proposed system. Meanwhile, it indicates that edge imaging can achieve higher contrast on biological samples. This work demonstrates the system’s potential for wide applications like target recognition and image enhancement, laying the foundation for hyperspectral phase edge microscopy.

光学差示显微镜的高光谱相位成像

边缘检测是新兴图像处理技术的关键。在这里，我们提出了一个双通道光学微分系统，忠实地检索二维（2D）图像的完整边缘。该系统利用改进的Wollaston棱镜，与高光谱成像（HSI）兼容，能够在450- 750nm范围内实现30个光谱通道的实时相位成像。实验结果表明，该系统将图像的峰值信噪比（PSNR）提高了6 dB以上。同时，表明边缘成像可以在生物样本上获得更高的对比度。这项工作证明了该系统在目标识别和图像增强等广泛应用方面的潜力，为高光谱相位边缘显微镜奠定了基础。
