SPIE Proceedings, 2009
This paper describes how a Digital Holographic Projector is designed and implemented to project two-dimension virtual images onto the volumetric display media. In this research, we focus on the method to create 3D models, diffractive algorithm and the display media.

Three-dimensional color holographic display
Applied Optics, 1999Three-dimensional (3D) color holograms are recorded in a cerium-doped, strontium barium niobate (SBN:60) photorefractive crystal. These holograms are shown to reconstruct true color reproductions of the original object with an observable field of view of 37 degrees.

Holographic Display using Volume Holographic Recording Medium
Imaging and Applied Optics 2018 (3D, AO, AIO, COSI, DH, IS, LACSEA, LS&C, MATH, pcAOP), 2018We propose a holographic display technique that reproduces complex optical field by combing analog hologram and digital referencing. In the proposed method, large number of basis light are pre-recorded in a volume holographic recording medium and they are optically addressed and reconstructed by using a spatial light modulator.

Holographic See-Through Displays
Digital Holography and Three-Dimensional Imaging 2019, 2019See-through displays, including head-up displays (HUD) and augmented reality (AR) displays, allow the viewer to see both the natural world and a projected image thanks to a combiner element. To offer larger field of view (FOV) and an increased eye box, holographic combiners have been used in the past.

Wide angle holographic video projection display
Optics Letters, 2021Holographic projection displays provide high diffraction efficiency. However, they have a limited projection angle. This work proposes a holographic projection display with a wide angle, which gives an image of size 306 m m × 161 m m at 700 mm and reduced speckle noise. The solution uses single

3D digital holographic display
The 17th Annual Meeting of the IEEELasers and Electro-Optics Society, 2004. LEOS 2004., 2004This study presents a 3D display system based on phase-shifting digital holography. This work also shows optical recording (within 30 frames/s) of a temporally changing 3D object and its numerical reconstruction. Thus, the system can be used for real-time recording, data transmission, and reconstruction of 3D object.

Ultrasonics, 1968
Abstract This is a short description of an optical holographic technique for storing a number of images on a single photographic plate. At present used for three-dimensional reconstruction of ultrasonic uterus scans, the system has potential for many other non-medical applications.

Holographic - Liquid Crystal Displays
SPIE Proceedings, 1989This paper describes a new family of displays which combine the versatility of liquid crystal displays with the 3-D perception and look-around conveyed by holograms. Results obtained with computer generated stereograms, coupled to dynamic scattering and twisted nematic displays, will be discussed together with possible applications.

Holographic panorama display system
2015 IEEE International Conference on Consumer Electronics - Taiwan, 2015In this paper, we proposed a holographic panorama display system. The presented scheme uses panorama technology display a holography images on the HoloAD platform. We adopt color correction method to perform image pre-processing and then find the feature points of the input image and match with each other.
