摘　　要：激光全息图像防伪产品，因其可目视直观识别，在市场上广为推崇，随着相关技术的发展，全息制品的开发也日新月异，一方面，激光全息制版技术不断革新，如计算机全息图、双光束雕刻全息图、真彩色全息图、合成全息图、密码全息图等都可以应用于透明全息技术，This paper mainly give an introduction of transparent holography, transparent holographic material and manufacturing technique of nanometer film. Transparent holograph refers to the holographic product Imaged on the transparent material. The holographic grating, formed on the surface of the transparent material after mould pressing, enables people＇ s eyes to see the reappeared laser holograph when It is illuminated by the sunlight or other kinds of light. A kind of nanometer material is used to make the transparent holograph. Therefore, the transparent holographic material has a stable holographic image, a better anti-friction and anti-erosion capacity. The manufacturing procedure of nanometer film is very strict and complicated. Thus the material is difficult to replicate and can enhance the anti-counterfeiting effect.
