A projection-type holographic light-field (LF) display is a full-parallax, full-color, and glass-free three-dimensional (3D) display with a holographic optical element and a projector. The display has unique characteristics, including transparency; however, a rapid calibration method has not yet been established. In this paper, we propose a rapid calibration method for a holographic LF display without sacrificing its accuracy. The proposed method performs calibration via the projection of binary sinusoidal patterns whose frequencies are iteratively and hierarchically upconverted. Compared to the conventional method, in the proposed method, the required number of projections is reduced from linear to logarithmic with the projector’s resolution. We confirm the successful reconstruction of the 3D image using the proposed method.
