摘要
为了提高产品防伪包装设计效果,提出基于激光干涉光刻技术的产品防伪包装设计方法.利用光纤耦合激光传输控制多光束干涉信息,基于光纤波导分束形成技术,集成处理光束传播路径,基于光束振幅、相位和偏振联合调制方法,提取产品防伪包装的防伪状态特征量,基于振幅型或相位型的微结构衍射单元阵列传输方法,构建激光干涉光刻模型,实现四光束、五光束和六光束的多光束激光防伪.测试结果表明,所提方法的被篡改率最低为0.05％,解密时间较短,均在30 ms左右,MSE为0.673％,PSNR为47.40 dB,SSIM为0.975,采用该方法进行产品防伪包装设计,提高了产品的激光防伪能力,降低被篡改率.
Abstract
In order to improve the design effect of product anti-counterfeiting packaging,a design method of prod-uct anti-counterfeiting packaging based on laser interference lithography was proposed.Multi-beam interference infor-mation is controlled by fiber-coupled laser transmission,based on fiber waveguide beam splitting forming technology,integrated processing of beam propagation path,based on beam amplitude,phase and polarization joint modulation method,the anti-counterfeiting state characteristic of product anti-counterfeiting packaging is extracted,and the laser interference lithography model is constructed based on amplitude or phase microstructure diffraction unit array transmis-sion method.Multi-beam laser anti-counterfeiting of four beams,five beams and six beams is realized.The test re-sults show that the lowest tampering rate of the proposed method is 0.05％,the decryption time is short,all about 30 ms,MSE is 0.673％,PSNR is 40.40 dB,and SSIM is 0.975.This method is used to design the product anti-counterfeiting packaging,which improves the laser anti-counterfeiting ability of the product and reduces the tampering rate.
