| Summary: | 碩士 === 國立臺灣大學 === 光電工程學研究所 === 102 === A 3D light field display system requires several design modifications to achieve the multi-view characteristic of a 360&;#730; 3D image. While certain light field display utilized a high frame rate projector&;not;&;not; or many micro projectors to achieve the modifications, they also drastically increased the cost of the system.
This thesis discusses the use of an optical simulation software to analyze different parameters in a light field display. First, different system configurations can affect the displayed image quality. Improving the geometric structure of the reflective screen can also decrease the frame rate requirement of the system. Since images projected and reflected from a tilted screen can result in image distortion, this thesis focuses on the analyses of different parameters to correct the distortion while maintaining the original dimensions of the 3D image.
Optical simulation software further allows studies of sub-images within a light field display and the viewing angle of the system. Varying the diffusion angles of the reflective screen can correct blurred image and non-uniform brightness within the image. In addition, the receiver distance can help to quantify the amount of image distortion. This research formulates a quantitative method that can be used as an indicator for determining the quality of sub-image realignment and other image properties.
Future studies can incorporate optical components into the system to further decrease the need for high frame rate projector. Multi-disciplinary cooperation, such as utilizing a tracking device to achieve real-time image correction by using previous image distortion data.
