Medical applications of holographic visual displays
Journal of Physics E: Scientific Instruments, 1969Holography permits the recording of a number of separate images on a single photographic plate, a technique known as holographic multiplexing. Depending on the method of producing the hologram, the images can be reconstructed so that they may either be viewed simultaneously in a predetermined array, or else viewed sequentially by altering the viewing ...

The invention relates to a holographic display (3) for storing and reproducing a spatial structure. Said structure comprises a holographic screen (1) forming the master hologram, and a projection device (2) which lights up the holographic screen in order to reproduce the spatial structure. According to the invention, the holographic display consists of

Holographic-laser-drawing volumetric display
2016 IEEE 14th International Conference on Industrial Informatics (INDIN), 2016We propose a holographic-laser-drawing volumetric display using a computer-generated hologram displayed on a liquid crystal spatial light modulator and multilayer fluorescent screen. The holographic-laser-drawing technique has enabled three things; (i) increasing the number of voxels of the volumetric graphics per unit time; (ii) increasing the total ...

An updatable holographic three-dimensional display
Nature, 2008Holographic three-dimensional (3D) displays provide realistic images without the need for special eyewear, making them valuable tools for applications that require situational awareness, such as medical, industrial and military imaging. Currently commercially available holographic 3D displays use photopolymers that lack image-updating capability ...

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.

Large holographic displays as an alternative to stereoscopic displays
SPIE Proceedings, 20083D displays comprise stereoscopic displays and holographic displays. Eye convergence and accommodation are important depth cues for human vision. Stereoscopic displays provide only convergence information whereas holographic displays also provide accommodation information.

Foveation in near-eye holographic display
2018 International Conference on Information and Communication Technology Convergence (ICTC), 2018Foveation is applied for the near-eye holographic display to relieve the requirement of the computing power and the space-bandwidth-product. Foveated point cloud data reduces the computational load in hologram synthesis and the foveated holographic display provides field of view exceeding the given space-bandwidth-product.

Holographic Displays for Computer Assisted Tomography
Journal of Computer Assisted Tomography, 1977Generalized holographic methods may be used to provide three-dimensional displays from a series of adjacent tomograms. Two such methods are described. In the first method, the tomograms are simultaneously recorded as a single "space-multiplex" hologram, which thus reproduces the N images in proper relation to each other in space.

Where Is My Digital Holographic Display?
Computing in Science & Engineering, 2008Are high-resolution digital holographic displays just around the corner? In the 1990s, two hurdles seemed to be preventing the practical implementation of computational holography techniques: computational workload and hardware projection capabilities. Are these hurdles still in place?

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.
