Principle And Design Of Optical Diffusing Device

Optical diffusing device have attracted the attention of scientific researchers from the establishment of the theory. With the emergence of related research results and innovative technology, optical diffusing device gradually be applied in various fields of our daily life, such as display, lighting and photoelectric detection. Now, many consumer electronics devices contain a number of optical diffusing devices. Importantly, for optical diffusing device, the capability of controlling light field distribution in specific direction, and the performance of modeming optical image information in space, has inspired scientific researchers apply it to the optical lighting and display field, including beam shaping,3D display technology, directional backlight technology, etc. In recent years, optical diffusing device technology changes each passing day with widely application. It is the design and manufacture of optical directional diffusing device that is promising research direction in future application.In this paper, the topic is the optical diffusing device applied in 3D display technology. Comparing the scattering theory of optical diffusing devices involved in different 3D display technology, explored the micro-structure optical diffusing device design method, and put forward various schemes of optical diffusing device based on micro-structure parameters designing. At the same time, we considered the coherence of lighting source as a condition to discuss the design and optimization method of the micro-structure optical diffusing devices, and confirmed the design method of optical diffusing device with randomly distributed structure parameters. Finally we realized the scattering with a certain amount of diffusing angle and uniformity. Moreover, it is described in detail that the process from confirming design principle, building simulation model, establishing design method, optimization of parameter choice, building sample processing system to testing the design method.With the design and optimization method of optical diffusing devices more and more advanced, to verify the exactness and to analyze performance of optical diffusing device by establishing processing system will be the next step. It will make the design method satisfy the design requirements of all kinds of application better. Therefore, after the extensive reference in existing micro-nano scale manufacturing technology, we applyed UV exposure curing to manufacture. And explored the processing technology of UV exposure curing. Then UV light curing processing system was established, and we put forward the manufacture processing technology of optical diffusing devices correspondingly. Finally, a preliminary analysis of the optical device performance was made, which laid a foundation for the following research work.
