本文提出紧贴加密的新方法 ,将加密位相板紧贴全息干版 ,使全息记录的物光和参考光同时获得位相调制 ,不但提高了全息图的防伪能力 ,而且由于位相板紧贴全息图 ,解密时对位相板只需进行二维甚至一维的调节 ,即可获得原物光的共轭再现 ,避免了对位相板繁琐的多维复原调节 ,增强了实用性。文中给出了透射全息图和反射全息图参考光的加密设计方案 ,由于对参考光进行恰当的共轭设计 ,相应的记录过程并不复杂
In this paper, we put forward a new method to keep close to encryption, and put the encrypted phase plate close to the holographic plate, so that the phase modulation of the holographic recorded object light and the reference light can not only improve the anti-counterfeiting ability of the hologram, , Decryption of the phase plate only two-dimensional or even one-dimensional adjustment, you can get the conjugate reproduction of the original light, to avoid the tedious multi-dimensional phase adjustment plan, enhance the usability. In this paper, the design scheme of transmission hologram and reflection hologram reference light is given. Due to the proper conjugate design of reference light, the corresponding recording process is not complicated
