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.

Sparse holographic imaging for an integrated augmented reality near-eye display.
Applied Optics, 2023Diffraction is the main physical effect involved in the imaging process of holographic displays. In the application of near-eye displays, it generates physical limits that constrain the field of view of the devices.

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.

Holographic Moving Map Display
Optical Engineering, 1974A high brightness display is achieved using tungsten sources to read out phase image plane holograms. Full color is provided by using three superimposed component holograms derived from three primary color separation object transparencies of the original subject.

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

Abstract : A head-up display system as used by an aircraft commander must provide a simulation of the real-world exterior to his vehicle, and, at the same time, represent any change in his attitude with respect to a predetermined segment of this real world. In the particular case of an aircraft landing approach, one can characterize the pilot's view of
