Abstract

Governments in all countries of the world today want organized and controlled societies that operate under a single set of rules and commands. Many governments around the world want and seek information that will allow them to control social groups and populations. Governments around the world set up ghost companies that were created to mislead the public and then collect information, data and then data from various sources or in collaboration with other third parties around the world. Somewhere here the game is changing, companies that are set up for information analysis often work for the benefit of third parties and governments. In a globalized world it is difficult to control the flow of data from both the extraction source and the final recipients.

Summary

Introduction

As various fields using optics have been actively developed, the demand for optical instruments has been increasing. In this study, the curvature of the lens was measured and the spherical wave was created to match the curvature of the lens to produce a uniform pattern on the lens surface with curvature, creating a periodic nanopattern through laser interference lithography on the top of the lens. As a basic technology for producing large-area nanopatterns on a surface of a curvature optics, PR coating was processed using spin coater on the surface of the lens, and the technology of fabricating nanopatterns uniformly on the surface of the lens, through the adjustment of the lens focal length of laser interference lithography to fabricate the anti-reflective pattern was proposed and fabricated [3,4,5].
