An automatic geometrical calibration approach has been developed to calibrate a multiprojector-type light field (LF) display automatically and accurately. The calibration framework based on image mapping is detailed, which transfers the calibration of three-dimensional (3-D) scene into the calibration of two-dimensional image in the diffuser interface. A multiprojectors-type LF display prototype is applied to implement the experimental calibration. Comparison results of the reconstructed 3-D scene before and after calibration show that a better overall performance is obtained through the proposed calibration approach. [ABSTRACT FROM AUTHOR]

A scalable system to achieve large-sized light field three-dimensional display using multi-projectors and directional diffuser is presented. The system mainly employs an array of mini-projectors projecting images onto a special cylindrical directional diffuser screen. The principle of light field reconstruction, configuration of multi-projectors style, and characteristics of directional diffuser are explicitly analyzed, respectively. A prototype of a piece of equipment in mini-cinema class is proposed, with 100 mini-projectors and a special cylindrical directional diffuser performing different diffuse angles in horizontal and vertical directions. Bright and large-sized three-dimensional images displayed by the system can be observed at different horizontal viewing positions around the cylindrical display area with stereo parallax and motion parallax.

The reproduction of computer-generated hologram (CGH) with white light source was realized using a liquid crystal panel instead of holographic film. The Burch-coding CGH was achieved by simulating the interference of a digital image and virtual reference light, displayed on liquid crystal displays and illuminated by a white light-emitting diode. The system is compact and the reconstructed images include full parallax. The full-parallax images of the Fresnel hologram computed with our algorithm were compared with the reproduced images by the rainbow hologram. The results implied this method was ready for the development of real-time three-dimensional color digital holography. [ABSTRACT FROM AUTHOR]
