Optical technology may provide important architectures for future computing, such as analog optical computing and image processing. Compared with traditional electric operation, optical operation has shown some unique advantages including faster operating speeds and lower power consumption. Here, we propose an optical full differentiator based on the spin–orbit interaction of light at a simple optical interface. The optical differential operation is independent of the wavelength due to the purely geometric nature of the phenomenon. As an important application of the fully differential operation, the wavelength-independent image processing of edge detection is demonstrated. By adjusting the polarization of the incident beam, the one-dimension edge imaging at any desirable direction can be obtained. The wavelength-independent image processing of edge detection provides possible applications in autonomous driving, target recognition, microscopic imaging, and augmented reality.

基于光的自旋轨道相互作用的与波长无关的光学全差分操作

光学技术可以为未来的计算（例如模拟光学计算和图像处理）提供重要的体系结构。与传统的电气操作相比，光学操作具有一些独特的优势，包括更快的操作速度和更低的功耗。在这里，我们提出了一种基于光在简单光学界面上的自旋轨道相互作用的光学全微分器。由于现象的纯粹几何性质，光学差分操作与波长无关。作为全差分运算的重要应用，展示了边缘检测的与波长无关的图像处理。通过调整入射光束的偏振，可以获得任何所需方向的一维边缘成像。
