A prototype system of head-mounted holographic display with multi-depth is presented. The system adopts the modified Gerchberg-Saxton algorithm to produce the phase-only functions on digital and analog types of spatial light modulators. Furthermore, the proposed system could achieve multi-depth by using human-eye focusing and zooming mechanism. Finally, the quality of images is also analyzed and evaluated.
