This paper presents a novel method of multi-spatial light modulator (SLM) holographic image display that enables wide angle reconstruction of images of real world objects. The image data are delivered by means of digital holography. The capture and display systems are arranged in a circular configuration. In order to support the proper information flow between the multi-sensor capture and multi-SLM display systems we perform analysis using the Wigner distribution function. We also consider a mismatch of the capture and display configurations as well as the visual perception of the displayed image. Experimental results based on the reconstruction of real world scenes are presented that demonstrate the validity of the theoretical solutions. A single camera is used to record the digital holograms, where the object is rotated between captures, and these holograms are then displayed on a circular configuration of SLMs. The results show the limitation of multi-SLM holographic displays in terms of visual perception. These problems arise from the limited angular distribution of the SLMs on a display circle and the presence of gaps between the SLMs.
