Abstract

Optical differentiation has the advantages of ultrahigh speed and low power consumption over digital electronic computing. Various methods for single and switchable-order differential operations have been extensively studied and applied in fields such as image processing and optical analog computing. Here, we report a parallel multiplexing scheme of optical spatial differentiations via a superposition of multiple complex amplitude filters. The isotropic and anisotropic first- to fourth-order differentiation multiplexing, as well as various types of differentiation multiplexing are demonstrated both theoretically and experimentally. Multifunctional differential operations can be generated simultaneously, realizing the extraction of multiple feature information about amplitude and phase objects. This proof-of-principle work provides an approach for multiplexing optical spatial differentiation and a promising possibility for efficient information processing.

基于叠加复振幅滤波器的并行复用光学空间分辨技术
与数字电子计算相比,光学微分具有超高速和低功耗的优点。各种单阶和可切换阶微分操作方法已被广泛研究并应用于图像处理和光学模拟计算等领域。在此,我们报告了一种通过多个复振幅滤波器的叠加实现光学空间微分的并行复用方案。我们从理论和实验两方面展示了各向同性和各向异性的一阶至四阶微分复用,以及各种类型的微分复用。多功能微分操作可同时产生,实现了对振幅和相位对象的多种特征信息提取。这项原理验证工作为光学空间微分多路复用提供了一种方法,也为高效信息处理提供了可能。

期刊介绍: Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods. Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following: -Optical Metrology- Optical Methods for 3D visualization and virtual engineering- Optical Techniques for Microsystems- Imaging, Microscopy and Adaptive Optics- Computational Imaging- Laser methods in manufacturing- Integrated optical and photonic sensors- Optics and Photonics in Life Science- Hyperspectral and spectroscopic methods- Infrared and Terahertz techniques
