| Abstract: | Volume holographic imaging system （VHIS） incorporates a volume hologram grating （VHG） as the critical optical field processing component in a new imaging system.High spectral resolution and high sensitivity in obtaining 3D information at multi-depths are achieved without time consuming scanning mechanism and complex reconstruction algorithms by utilizing the Bragg diffraction selectivity and degeneracy properties.We briefly introduced the system structures and principles,then we presented intensively on how these VHGs were devised and VHIS were configured into the qualified spectral VHIS （S-VHIS） and multiplexed VHG imaging systems.The superiorities over conventional imaging systems and the features to be improved of VHIS were summarized and discussed. |
