Any practical holographic display device relying on the MIT synthetic aperture approach will require timebandwith products far exceeding those available with single channel acousto-optic modulators (AOMs). A solution to this problem is to use a multichannel AOM, thus making use of the parallelism inherent in optical systems. It is now technically feasible to accomodate a large number of acousti...

A number of methods for producing holographic optical elements (HOEs) for use in projecting integral images in holographic stereogram printers are presented, with emphasis on application to Ultragram format one-step stereograms. Creation of HOEs to replace standard diffusion screens and enhance stereogram printer imaging properties and efficiency is discussed. Monolithic and integral holographi...

vidual studies seems an attractive option. By further optimization of the management of heart failure patients a large number of hospitalizations can be prevented, potentially resulting in an appreciable cost reduction and better quality of life for heart failure patients.

The hoes are widely used in the farms and home gardens in the United States. Many existing hoes are not ergonomically designed because they require a lot of back bending and wrist bending during use. Back bending often causes lower back injuries, and wrist bending often causes carpal tunnel syndrome. It can be very expensive to cure these injuries. The objective of this project is to reduce bac...

This paper reports the design and fabrication of transmission holographic optical elements (HOEs) for clock distribution. First, we have studied and fabricated a multi-focus doublet HOE. The aberrations due to the wavelength shift between recording (= 488 nm) and reconstruction ( = 780 nm) have been minimized by an appropriate recording and readout geometry. The diffraction efficiency has been ...
