Displays holography

Display holography is by far the most familiar and weU-developed holographic appHcation to date with several museums dedicated to holographic art.

The final step in formation of 3D ultrasound images is to display the data so that the inherent voxel information is communicated accurately. Commonly, simple rotation of the object on the computer monitor provides some 3D effects. To further enhance the 3D outcome of the images, stereoglasses have been applied (Martin et al. 1995 Nelson and Pretorius 1995). Projection of images by optical holography enables the observer to move around the object and examine the spatial relationships from different viewpoints (Baum and Stroke 1975 Koivukangas et al. 1986 Redman et al. 1969). A typical setup of a 3D ultrasound system is shown in Figure 23.2. 

Holograms have many uses besides the display of three-dimensional images. Applications include industrial testing, precise measurements, optical data storage, and pattern recognition. A presentation of the applications of holography is given in Section V. 

Three-dimensional (3-D) display is an ultimate display technology. From the theaters to TVs at home, to naked eye mobile devices, 3-D displays [1-3] have been gaining popularity in our daily lives. In this chapter, we will outline the basic operation principles for generating depth perception, in order to reahze 3-D displays. Several types of 3-D display devices stereoscopic displays, autostereoscopic displays, integral imaging, holography, and volumetric displays are discussed. 

Further development of such studies resulted in the self-reinforced plastics based on LC polymers with main-chain mesogenic groups and laid a foundation for the use of comb-shaped LC polymers as new photoactive materials for optics, optoelectronics, photonics, holography, display technology, telecommrmications systems, and other no-less important areas of modem engineering.

Thomas Felder obtained a PhD in physical chemistry from the University of Pennsylvania in 1983 and joined DuPont later that year. He has worked in the fields of silver halide chemistry, xerographies, lithographic printing, fluorochemistry, NIR-induced thermal transfer, and holographies, and holds a number of patents in these fields. He was a member of DuPont Holographies from 1996-2002. He is a research associate working on novel imaging materials in the DuPont Displays Division.
