Dual-View Integral Imaging 3D Display Based on Multiplexed Lens-Array Holographic Optical Element
Applied Sciences, 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 ...

Speckle Noise-Free Interconnective Holographic Projection
Photonics, 2022 Generally, speckle noise is regarded as unavoidable in holographic projection, and it results from unexpected high spatial frequency components of diffracted light at the sharp edge of pixel openings in a spatial light modulator.
