In this study, we offer a new type of hyper-realistic holographic display system that simultaneously displays both 3D images and AR images. The proposed ultra-realistic combines 360-degree computer generated (CGH) content to be reconstructed from an SLM (2D image) spatially projected microdisplay, allowing users watch clearly blended movie without crosstalk. To validate the display's image characteristics with varied depths, ruler-based spatial depth measurement method was used show...
In this study, we introduce a design for near-eye, wearable display (HMD: head mounted display) that can automatically control the user's interpupillary distance (IPD). addition, demonstrate test-bed module AR based on proposed design. Both adjustment accuracy and viewing effect through matching between user’s eyes are evaluated by experience in actual wearing of module. We left right eye pupils be measured adjusted using set IR camera sensors micro-actuator proposed. A half-mirror unit to...
Electronic holographic displays can reconstruct the optical wavefront of object light, exhibiting most realistic three-dimensional (3D) images, in contrast to conventional stereoscopic displays. In this paper, we propose a novel, near-eye 3D display (NEHD) applicable AR/MR/holographic devices and experimentally demonstrate proposed module’s performance with 360° full-viewed movie at 30 fps. To realize high-quality reconstructed (H3D) also an advanced amplitude-modulating (AM) encoding scheme...
Abstract Refractive index stands as an inherent characteristic of a material, allowing non-invasive exploration the three-dimensional (3D) interior material. Certain materials with different refractive indices produce birefringence phenomenon in which incident light is split into two polarization components when it passes through materials. Representative birefringent appear calcite crystals, liquid crystals (LCs), biological tissues, silk fibers, polymer films, etc. If internal 3D shape...
The presence of monocular depth sense is identified with a light field imaging system which can project up to 8 different view images simultaneously viewer’s each eye. subjects’ eyes increases further as the number projected eye more, though increasing rate somewhat for subjects. diopter values exceed more than those real object exceeds six binocular viewing while it eight viewing. that These results assure natural condition be incorporated in systems. are derived from 7 subjects under age...
A hand-held camera that is capable of acquiring full parallax multiview images introduced. Since the based on spatial sharing aperture stop a digital camera, it easy to manufacture. The spatially shared by 2D high-speed liquid crystal (LC) shutter array fixed front surface objective. consists 8×8 LC shutters acquire images. equivalent optical configuration not different from parallel-type array. Each has an equal disparity its neighbors and detector resolution camera. small enough be used in...
