Abstract

This work describes a multi-plane iterative algorithm to extend depth of focus (DOF) for curved image reconstruction of Fresnel computer-generated hologram (CGH) on a liquid crystal on silicon spatial light modulator (LCoS-SLM). Compared to the depth of focus in a conventional CGH, the proposed method can improve the DOF at least 2 times in the near-field image reconstruction. The property of wide depth of focus makes it possible to reconstruct the real images displayed on a curved surface. No extra lens set which is usually used in head-up display and projection display is needed. The CGH customized design is feasible and applied for various curved displays and applications.
