摘要： An enhanced optical interference pattern, such as a diffraction grating, is incorporated into a photodefineable surface by shining three or more beams of coherent light from a single source at a photodefinable surface, such as a photosensitive emulsion/photoresist covered glass or an ablatable substrate and mapping the diffraction grating pattern to the photodefinable surface. Mapping of the optical interference pattern is created by interference of three or more light beams, such as laser light or other light sources producing a suitable spectrum of light. The mapped photodefinable surface can be used to create embossing shims. The embossing shim can then be used to emboss film or paper. The embossed film/paper can be metalized and laminated onto a substrate to create a product that has shifting patterns at a variety of viewing angles when exposed to white light.

摘要： Laser ablation to direct write dot matrix holographic patterns onto the surface of polymeric coatings deposited on an embossing cylinder is described. The desired holographic pattern is ablated by interfering at least two laser beams directly onto the polymeric coating of the embossing cylinder in the pixel-by-pixel manner. The direct write laser ablation technique eliminates the size limitations of the holographic pattern created on the surface of the embossing cylinder, the need to combine smaller images to create a larger shim and the very need to use the shims, since large seamless embossing cylinders can be directly pixel-by-pixel ablated with larger sized images of great variety. The polymeric coatings for further direct write laser ablation can be deposited onto the embossing cylinder by various methods, including, but not limited to, molding or coating.
摘要翻译：描述了激光烧蚀以将写入点阵全息图案直接写在沉积在压花圆筒上的聚合物涂层的表面上。通过以逐像素的方式将至少两个激光束直接干涉到压花圆筒的聚合物涂层上来消除所需的全息图案。直接写入激光烧蚀技术消除了在压花圆筒表面上产生的全息图案的尺寸限制，需要组合较小的图像以产生更大的垫片，并且非常需要使用垫片，因为大的无缝压花圆筒可以直接逐个像素地消除与大尺寸的图像的大品种。用于进一步直接写入激光烧蚀的聚合物涂层可以通过各种方法沉积到压花滚筒上，包括但不限于模制或涂覆。

摘要： Device, method, and system for recording diffractive high resolution text, pictorial, and/or other graphical information is provided which is particularly suited to recording information that would be difficult to reproduce by typical counterfeiting methods. The information recorded may be used to authenticate the recorded item, or indirectly, an item to which the recording is attached. Such items may include legal, financial and commercial instruments, credit cards, and packaging for such items as software, art, and other items where forgery of the item may be a concern. In one embodiment of the invention light is selectively passed by a shutter, and a spatial filter then cleans the beam to remove undesirable frequency components. A liquid crystal display (LCD) dynamically receives a data stream from a computer where each of the displayed data values presents an optical characteristic (for example density, phase, or polarization) to the filtered beam and causes diffraction into a plurality of diffracted beams, the character of which is dependent on the data displayed. A mask selectively passes only predetermined ones of the beams so that only frequency components that will generate the desired optical interference fringes are allowed to pass. Additional optical components receive the passed beams and redirect them to overlap at an output plane to form interference fringes. These interference fringes can have a very high spatial frequency so that extremely fine lines or small objects, including text and graphics, can be recorded.

摘要： A method and apparatus for producing a hologram using a two-beam laser interference exposure process, comprising the steps of using as a light source a femtosecond laser having a pulse width of 900-10 femtoseconds and a peak output of 1 GW or more and capable of generating a pulse beam at or close to the Fourier transform limit, dividing the pulse beam from the laser into two by a beam splitter, controlling the two beams temporally through an optical delay circuit and spatially using plane and concave mirrors each having a slightly rotatable reflection surface to converge the beams on a surface of or within a substrate for recording a hologram at an energy density of 100 GW/cm2 or more with keeping each polarization plane of the two beams in parallel so as to match the converged spot of the two beams temporally and spatially, whereby a hologram is recorded irreversibly on the substrate formed of a transparent material, semiconductor material or metallic material.
