This system demonstrates improved resolution and depth of field in light field imaging, suggesting new possibilities for image capture.
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.
