论文摘要
级联操作在传统的电子计算系统中起着重要的作用，以实现高级策略。在这里，我们将级联操作的概念介绍给全光空间模拟计算。第一阶操作的单个功能很难满足图像识别中实际应用的要求。通过级联两个一阶差分操作单元，实现了全关光二阶空间区分子，并证明了振幅和相位对象的图像边缘检测。我们的方案为发展紧凑的多功能区分和高级光学模拟计算网络提供了可能的途径。
Cascaded operations play an important role in traditional electronic computing systems for the realization of advanced strategies. Here, we introduce the idea of cascaded operations into all-optical spatial analog computing. The single function of the firstorder operation is difficult to meet the requirements of practical applications in image recognition. The all-optical second-order spatial differentiators are implemented by cascading two first-order differential operation units, and the image edge detection of amplitude and phase objects are demonstrated. Our scheme provides a possible pathway towards the development of compact multifunctional differentiators and advanced optical analog computing networks.
