ABSTRACT
In this paper, we propose a method to increase the field of view (FOV) in holographic display. Different from traditional method, large-sized computer-generated hologram (CGH) is generated, and function screen used proposed method. The CGH formed by superposition interference fringes. diffraction boundary angle interferogram set be equal maximum reconstructed light. reconstruction, three spatial light modulators (SLMs) arranged side linear configuration are load CGH. functional for eliminating seams between SLMs further enlarging With after each image point expanded, so that FOV can increased effectively. Experimental results prove feasibility
