This case study offers a detailed analysis of Autism and the effects of Holographic Kinetics on an Autistic Child with extreme Aggressive Behavioral Disorder.

We introduce a maskless lithography tool and optically-initiated diffusive photopolymer that enable arbitrary two-dimensional gradient index (GRIN) polymer lens profiles. The lithography tool uses a pulse-width modulated deformable mirror device (DMD) to control the 8-bit gray-scale intensity pattern on the material. The custom polymer responds with a self-developing refractive index profile that is non-linear with optical dose. We show that this nonlinear material response can be corrected with pre-compensation of the intensity pattern to yield high fidelity, optically induced index profiles. The process is demonstrated with quadratic, millimeter aperture GRIN lenses, Zernike polynomials and GRIN Fresnel lenses.

Holographic data storage (HDS) is transitioning to second-generation technologies in order to meet the demands of big data. Akonia Holographics is developing an advanced HDS demonstrator platform featuring a high NA recording geometry, novel multiplexing methods, and coherent channel techniques to meet these challenges.

Immersive stereoscopic imaging requires sharp wide field images, special software, and high resolution displays. Examples of some successful image capture, splicing, viewing, hosting, and posting techniques used in digital stereoscopic panoramic photography are given. Image capture uses camera movements that approximate natural eye positions reasonably well by using manual or motorized gimbal mounted systems designed for the purpose. Processing requires seamlessly stitching dozens or hundreds of images into left and right panoramas. Creating stereoscopic images over 50 mega pixels benefits from programmable motorized camera mounts. The 2 gig limit of TIFFs is often exceeded and requires the use of GigaPan.org hosting technologies. Gigapixel stereoscopic images are viewed as a single whole while many small files are quickly uploaded to improve the sharpness of the areas viewed and may be seen at 3d-360.com. Immersive stereo contents, active scrolling and deep zoom capabilities take stereoscopic photography from snapshots into the realm of immersive virtual presence when combined with modern web and display technologies. Scientific, artistic, and commercial applications can make effective use of existing stereoscopic displays systems by using these extended capabilities.

With the arrival of the “World Wide Web,” we have witnessed a transition toward a truly global perspective with respect to electronic health records. In recent years, much more discussion has focused on the potential for international virtual electronic health records and what is required for them to become a reality in the world today (Kilman & Forslund, 1997). As the Internet becomes more ubiquitous and Web-enabled, we see access to electronic health records using these technologies becoming more commonplace. Even so, these Web-enabled health records still remain technologically isolated from other medical records in the distributed continuum of care; much of the standardization challenge still stands before us. We have witnessed startling technological advances, but we still face considerable obstacles to the goal of having globally standardized electronic health records. In this chapter we describe some of the issues associated with Web-enabled health records, the role of standards in the evolution of Web-enabled health records, and some of the barriers to the development of globally accessible electronic health records. We discuss possible ways to overcome these barriers and the kinds of benefits and opportunities that global health records will help provide. The global scale perspective makes more evident the very real and potentially tragic consequences of prolonged and unnecessary delays in deploying these technologies. Therefore, in an effort to promote a fuller consciousness of health safety, the chapter concludes with a comparative look at the negative impact of impediments in the movement toward global extensible electronic health records.Request access from your librarian to read this chapter's full text.

This study attempts to evaluate the efficacy of undergraduate public relations programmes in the United States. The study surveyed 155 public relations educators and practitioners to determine their impressions on factors such as whether students are being imparted the knowledge and experience to become public relations practitioners, the knowledge and skills respondents thought students ought to possess to become successful professionals, the skills new graduates should possess, and the characteristics of the public relations profession. Results revealed agreement among educators and practitioners about the subjects that should be taught in undergraduate public relations programmes, including the knowledge and skills recommended by the Commission for Public Relations Education. Respondents did not agree on the best career plan for future public relations professionals. However, a majority felt that majoring in public relations with a minor in business was the best thing for students who want to work in this field. Respondents felt that not all of the subjects they deemed important were currently being taught in all public relations programmes. Both practitioners and educators agreed that graduates were well trained in the use of new technologies for public relations. However, the percentage of practitioners who felt that graduates were prepared to enter the public relations profession was considerably lower than educators.

In the last several years, holographic elements have been introduced into a wide array of display applications. Holographic Reflectors are incorporated with liquid crystal displays to shift optimum viewing angle away form specular glare and raise brightness by concentrating light at a convenient viewing angle. Reflectors can be produced in blue, green, gold, red, or white colors. Denso GlassVision projection screens incorporate transmission holograms to efficiently direct projected light to the viewer in a screen that reverts to clear glass When the projection image is turned off. JVC has introduce da large-screen HDTV that uses a holographic color filter to separate blue, green, and red light from the illumination beam, and direct the sorted colors to the appropriate color pixel, raising brightness with a passive component. Most recently, HOE prototypes have been produced to improve the efficiency of portable liquid crystal color display. Front diffuser are affixed to the face of reflective color LCDs and direct output light from the LCD to the viewer at a convenient viewing angle in a concentrated view cone. Reflective Colors Filters are pixelated diffuse reflectors internal to the LCD structure and aligned to the LCD matrix. These reflective filters provide higher brightness, larger color gamut, and better color saturation including a holographic grating are under development to provide wider view angle in direct-view LCDs.© (2001) COPYRIGHT SPIE--The International Society for Optical Engineering.

When I first started making holograms in 1974 I was searching for direction in my art. After a few encounters with holograms I realized many diverse disciplines could come together to form a kind of unifying clarity of many interests. It turns out, this can of worms encompasses a universe, within a universe, within a universe.

The use of diffraction effects as decoration has been investigated for a long time before lasers and holography were ever dreamed of. A brief history of applications of diffraction from the 1700s to the present is given along with a review of various patents and products using diffraction gratings before the age of holography.
