P‐85: Spatial‐Resolution‐Improved Light‐Field Imaging System Using Virtual‐Moving Microlens Array without Decrease of Angular Resolution

Abstract

We propose resolution-enhanced light-field (LF) imaging system utilizing the virtual-moving microlens array (MLA). According to the polarization direction of the incident ray, the virtualmoving MLA can shift sampling positions without physical movement. In our LF imaging system, the spatial-resolution of the reconstructed images using virtual moving MLA was improved by four times while maintaining angular resolution compared with that obtained with conventional LF imaging system. The real-time imaging capturing at video frame rate can be implemented by using fast switching polarization control layer.
