Abstract

As microdisplay systems get more affordable for various applications, needs of larger field-of-view becomes important typically for a near-to-eye application. However, for near-to-eye application, pincushion distortion is hard to avoid due to the high magnification of optics for the systems. In this paper, we propose a novel architecture and algorithm for real-time correction of the distortion without using traditional radial and tangential modeling. We confirm that the performance of our proposed scheme which is implemented on field programmable gate array (FPGA) by testing with FHD liquid crystal on silicon (LCoS) panel.
