Spatiotemporal multiplexing method for big images observation in wide angle holographic display

Abstract

In the paper a holographic display system with extended viewing angle and capability to reconstruct images with no size limitation is presented. The display is constructed from three spatial light modulators (SLM) arranged on a circle. For gap disposal in reconstructed images a beam splitter is used. The presented spatiotemporal multiplexing technique based on sequential illumination from different direction allows us to double their number. In experimental setup we have obtained a continuous holographic reconstruction in 2.5 times bigger viewing angle comparing to a single SLM utilization.
