摘要
光学加密技术是信息光学中理论知识拓展应用的教学重点,但传统的教学方式多以该技术的数理模型讲解为主,缺少实验装置的直观演示,学生难以理解光学加密的过程和应用效果,因此,本文设计了一套混合光学变换的信息加密实验平台,该平台利用自主编写的仿真软件实现图像的加密、解密仿真与密钥作用的探究;利用搭建的解密光路装置配合仿真实现光路解密。该平台服务信息光学的教学,可视化程度高、交互性强、操作简便,将理论模型实例化,且结合仿真与光路,有助于学生对光学加密技术的系统化、全面化理解,提高学生的自主探索能力和创新能力。
Optical encryption technology is the focus of information optics course to expand the application of theoretical knowledge,but the traditional teaching way is given priority to with the mathematical model of this technology on more,lack of experimental apparatus of visual presentation,students are difficult to understand the process and application of optical encryption effect.Therefore,it designs a set of hybrid optical transform information encryption experimental platform,the platform using the simulation software of independent writing.The realization of image encryption and decryption simulation and key role exploration;Use of scaffolding to decrypt optical path devices simulation realization of optical path.The service of information optics teaching platform,high degree of visualization interactive easy to operate,will instantiate the theory model,and combined with the simulation and the optical path,helps the student to the optical encryption technology systematic comprehensive understanding,improve the students’innovation ability and information technology application ability.
