Depth of Field Enhanced Integral Imaging Display System

Photonics
Large depth of field (DOF) is a core pursuit in integral imaging (InIm). In this paper, we propose a DOF-enhanced InIm display system comprising a transmissive mirror device (TMD), a semi-transparent mirror (STM), two 2D displays, and a micro-lens array (
