摘要： The micro-optical system of the synthesis of visual images claimed as the invention is primarily a device used to certify the authenticity of products and can be used efficiently to protect bank notes, securities, documents, plastic cards, bank charge cards, documentary, identification, and control stamps, and various consumer goods against counterfeit.
The micro-optical system in accordance with the claimed invention consists of a base with a single layer of flat optical elements, which have the form of flat off-axis Fresnel lenses with a paraboloid phase function or flat off-axis Fresnel lenses with a saddle-shaped phase function made in the form of microrelief and effecting, when the microoptical system is illuminated, the synthesis of images consisting of separate points exhibiting the visual effect of the motion of synthesized images when the base is tilted with respect to the observer.
The technical result consists in improved reliability of the visual control of the products protected using the claimed system due to the creation of easy-to-control effect of image motion combined with reduced thickness of the claimed system.
The invention can be implemented using the already available standard equipment.摘要翻译： 作为本发明的视觉图像的合成的微光学系统主要是用于证明产品的真实性的装置，并且可以有效地用于保护纸币，证券，文件，塑料卡，银行卡，纪录片，识别 ，并控制邮票和各种消费品打击假冒。 根据要求保护的发明的微光学系统由具有单层平面光学元件的基底组成，其具有抛物面相位函数的平面离轴菲涅耳透镜的形式或具有鞍形的平坦离轴菲涅耳透镜 形状相位函数以微观形式形成，并且当微光学系统被照亮时，合成图像，当基底相对于观察者倾斜时，由合成图像的运动的视觉效果的单独点组成。 技术结果在于提高了使用所要求保护的系统保护的产品的视觉控制的可靠性，这是由于创建了易于控制的图像运动效果以及所要求保护的系统的厚度的减小。 本发明可以使用已经可用的标准设备来实现。
