Dual-View Integral Imaging 3D Display Based on Multiplexed Lens-Array Holographic Optical Element
Applied Sciences (Switzerland), 2019 We propose a dual-view integral imaging 3D display based on a multiplexed lens-array holographic optical element (MHOE). A MHOE is a volume holographic optical element obtained by multiplexing technology, which can be used for dual-view integral imaging ...
