Integral imaging is one of the attractive autosteroscopic three-dimensional (3D) displays. The 3D image can be composed by integrating elemental images with different perspectives. Due to the geometry of integral imaging system, pseudoscopic imaging is an inevitable problem regardless of image type such as imaginary and real. Various methods are presented to improve the image quality and viewing parameters but few of trials for solving pseudoscopic imaging problem are presented. We propose and compare two methods for orthoscopic 3D real image reconstruction in integral imaging system using elemental image transformation. Theoretical analyses of elemental image transformation for 3D real image reconstruction are described in details and the experimental results are presented.
In recent years there have been many activities in the area of three-dimensional display because of their potential applications. Large storage three-dimensional display system using integral imaging and volume holographic storage is proposed. In addition to the large storage, the speckle reduction based on time averaging and the viewing angle enhancement are achieved by using the proposed display system. Experimental results are presented and optical parameters of the proposed system are discussed in detail.
We present an all optical photorefractive volume holographic processor for recognition of three-dimensional(3D) objects. The templates are recorded by use of a volume hologram in a photorefractive LiNbO3:Fe crystal located at the Fresnel diffraction region and correlated in real time with a 3D object illuminated by coherent light. Experimental results for recognition of 3D objects are presented and compared with conventional two-dimensional method.
