Abstract
We propose an active-switching light-field (LF) camera system that significantly extends the measurable depth range over conventional passive-optics-based LF systems by integrating a stacked geometric phase lens (GPL) module in a compact design. During elemental image acquisition and LF rendering, chromatic aberration in the focus-tunable GPL is compensated by adjusting the reconstruction depth and magnification for each color channel. Additionally, the optimal GPL operation sets are selected based on color-dependent depth-of-focus conditions. These optimizations enable the proposed GPL-based LF system to achieve full-color, depth-enhanced LF imaging while mitigating the typical trade-off between spatial resolution and depth of field limitations.
期刊介绍：
The Journal of the Society for Information Display publishes original works dealing with the theory and practice of information display. Coverage includes materials, devices and systems; the underlying chemistry, physics, physiology and psychology; measurement techniques, manufacturing technologies; and all aspects of the interaction between equipment and its users. Review articles are also published in all of these areas. Occasional special issues or sections consist of collections of papers on specific topical areas or collections of full length papers based in part on oral or poster presentations given at SID sponsored conferences.
