Floating depth and viewing angle enhanced integral imaging display system based on a transmissive mirror device

We propose a floating depth and viewing angle-enhanced integral imaging (InIm) display system based on a transmissive mirror device (TMD). The system consists of a 2D display, a micro-lens array (MLA), and a TMD. The light emitted by the proposed InIm display system is reconstructed into a floating 3D image by the TMD, and the floating 3D image has a greater floating depth than the conventional InIm display without sacrificing resolution. The issue of mutual restriction between the floating depth and resolution of the 3D image is solved. The positions of the MLA and the 2D display are reversed through the TMD imaging, which results in an improved viewing range and an improved viewing angle of the floating 3D images. The system expands the floating depth and viewing angle simultaneously without sacrificing resolution. The experimental results prove the feasibility of the proposed system.
