Abstract

We propose a geometric phase lens-based light field (GPL-LF) system that provides extended depth of field (DoF) and enhanced LF resolution by utilizing the polarization-dependent depth-switching operation with the geometric phase lens (GPL). The GPL-LF system enables user’s selective directional view or depth-reconstructed images with overcoming the traditional trade-off relationship between the achievable LF resolution and DoF in conventional LF imaging systems operated with passive lens.
