A volume holographic imaging system, apparatus, and/or method enables the projection of a two-dimensional (2D) slice of a four- dimensional (4D) probing object A 4D probing source object is illuminated to emit or scatter an optical field A holographic element having one or more recorded holograms receives and diffracts the optical field into a diffracted plane beam having spectral information A 4-ftelecentπc relay system includes a pupil filter on the relayed conjugate plane of the volume hologram and images the pupil of the volume hologram onto the front focal plane of the collector lens A collector lens focuses the diffracted plane beam to a 2D slice of the 4D probing source object The focused 2D slice is projected onto a 2D imaging plane The holographic element may have multiple multiplexed holograms that are arranged to diffract light from the corresponding slice of the 4D probing source object.
