- Multi-view 3D displays based on a limited number of pixels have the problem that the stereo-scopic image has a low resolution
because of increasing view number. To solve the problem of low resolution, we propose an optical approaching method that
focuses the width of a unit pixel by using a commercial spherical shape lenticular lens sheet and increases the effective resolution
by increasing the number of sources of light in the multi-view 3D display system based on projection type. The method was
performed in such an order that several main derivable parameters were defined, and, through the theoretical and experimental
result, the value of the contractible unit pixel width and the scalable effective resolution was derived in a given system
environment. As a result, for the case that the ray of light from the projector transmitted the 25 LPI lenticular lens sheet which has the pitch size 1.016 mm, the focused unit pixel width was 0.19 mm and the scalable effective resolution was, at most, 5
times wider than the original one. In addition, the range of depth of focus was 1.496 mm, which shows us the range of thickness
tolerances of commercial spherical shape lenticular lens sheet and sufficient optical alignment tolerances.
