▲ [19a-221B-4] An Estimation Method for Alignment of Non-parallel Plates based on Wave Optics
Keywords:Holography, Display Panel, Wave Optics
As the research and development of display systems are advanced, various functional panels are embedded in a single display product, and precise aligning between panels is becoming important in order to derive intended results when designing. Also, when attaching an optical element having a special function to a flat panel display, the accuracy analysis of the inter-panel alignment is the crucial keypoint and that is being studied by many researchers. In this study, we propose a method to analyze the alignment by estimating the degree, which is calculating by the positional correlation between the panels based on the wave optic analysis. Using this method, analyzing of the alignment degree of three-dimensional rotation is suggested using not only the method of measuring panel displacement and rotation in a two-dimensional plane but also the characteristics of a hologram which forms image precisely at a specific distance.
