Intelligent coded lock based on grating diffraction
The invention discloses an intelligent coded lock based on grating diffraction. The intelligent coded lock comprises a receiving screen, a light source, a grating, a ccd camera, a moving rod, a computer, a switch lock and a camera obscura. A light source is generated by a laser generator, diffraction light spots appear on a receiving screen after being diffracted by a grating, the distance between 0-level light spots and 1-level light spots is recognized through a computer, the number of the light spots on the screen serves as parameters to be compiled, the parameters are compared with preset parameters in the computer, and whether the lock is unlocked or not is determined; in addition, the light source wavelength, the grating constant and the distance between the grating and the receiving screen can serve as parameters for password combination, decoding difficulty of the coded lock is increased, and the safety level is improved.
本发明公开了一种基于光栅衍射的智能密码锁，包括接收屏，光源，光栅，ccd摄像头，移动杆，计算机，开关锁，暗箱；本发明以激光发生器产生光源，经光栅衍射后在接收屏上出现衍射光斑，通过计算机识别0级与1级光斑间距、以及屏上光斑数量作为参数进行编译，与计算机内预设参数进行比对，确定是否开锁；另外光源波长、光栅常数、光栅与接收屏距离也可作为参数进行密码组合，增加密码锁的破译难度，提高安全等级。
