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。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.
