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 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
