Pure Optical Blending Technology for VisSim

High resolution, large area displays are currently realized by tiling multiple projectors. Seamless transition between adjacent projecting areas is achieved by electronics blending, which is unable to correct artifacts in the transition regions especially for dark scenes. We propose a feasibility study of using optical blending techniques as potential solutions to the above problem. We plan to develop numerical simulation methods and MTF measurement techniques to quantitatively design and evaluate the blend quality. The success of the proposed research will benefit Christie with a clear understanding of optical blending technologies’ applicability in this area as well as contacts with a broader base of expertise at McMaster in optical materials technologies such as thin films and polymers. Christie may also benefit from new quantitative blend quality evaluation and design method superior than the existing empirical assessments done today, which are inadequate for IR or NVG use.
