It is well know that the counterfeit proof mark with high stability and security is needed by such things as credit card,ID card,trade mark,and so on Nowadays many counterfeit proof marks have been imitated and heavy losses have been caused to the state,enterprise as well as individual So an advanced technology of the image encryption and security verification for counterfeit proof is becoming a popular subject of study By using two random phase masks,it can encode a primary image into a complex amplitude and phase stationary white noise that impossible received by detectors only sensitive to light intensity to achieve the goal of security The method of checking the encryption image is to use optical 4F system or transferable correlator to decode and identify the image This is a simple,safe and practical way for image encryption and security verification and has a huge potential for development in the field of the state security and commercial secret [

信用卡、证件以及商标等都需要安全稳定的防伪标志。目前社会上的很多防伪标志因为技术含量低而经常被伪造,给国家、企业或个人造成巨大损失。于是,一种为防伪光学图像保密和作安全检查的技术就成为这个领域里的热门。利用两个随机相位掩模将振幅识别的初始图像编码为复振幅稳定的白光噪音,从而使仅对光强敏感的探测器无法接收,以达到保密的目的。对保密的光学图像进行安全检验的方法则是利用光学4F系统或联合变换相关器对图像进行解码或识别。这种方法具有很强的抗盲卷积性质,是一种简便稳妥而实用的图像保密和安全检查方法,在广大的国家安全和商业保密领域里具有很大的发展潜力。

Aiming at the characteristic of high reflectance and low transmittance (nearly zero) of the broken films of a light changeable material, a simple and precise method was used to measure and evaluate the quality of them. The optical dispersion of the broken films of light changeable materials was researched by micro analysis, and their mono chromaticity was described by using reflectance spectrum(400~700nm). The color index was calculated using the software developed by the author, which makes it possible to...

Aiming at the characteristic of high reflectance and low transmittance (nearly zero) of the broken films of a light changeable material, a simple and precise method was used to measure and evaluate the quality of them. The optical dispersion of the broken films of light changeable materials was researched by micro analysis, and their mono chromaticity was described by using reflectance spectrum(400~700nm). The color index was calculated using the software developed by the author, which makes it possible to quantitatively evaluate the optical properties. The result shows that the color tone of the broken films mainly focuses on green. The saturation and brightness of sample No.3 is the highest, but its color tone is somewhat yellow. The color tones of samples No.1 and No.2 are almost the same, with the sample No.1 being high in saturation and a little low in brightness, which is the most suitable material for making counterfeit proof marks.

针对光可变材料碎膜具较强的反射性且透射率近于零的特点 ,使用既简捷又准确的检测方法评价了碎膜样品的质量 ;利用显微分析方法研究了其色散光性 (即反射率光谱 ,40 0~70 0 nm) ,描述了其特有的单色性 ;再使用作者所设计的软件自动计算出颜色指数 ,从而可定量地评价其光性 .结果表明 :碎膜样品的色调主要集中在绿色 ,其中 3号样品的饱和度、亮度最高 ,但其色调偏黄 ;1 ,2号样品的色调一致 ,其中 1号样品颜色饱和度高、亮度稍低 ,最适合用作防伪标志的材料 .
