In 1830, the state legislature called on town leaders to "form a Fire Company to work a fire engine for the protection of buildings" in Willimantic. By 1832, the Willimantic Fire Engine Company had purchased an engine known as the "Deluge" and began a rich tradition of service to the people of Willimantic. Over the years, various fire companies were formed. From hand-drawn to horse-drawn to motorized equipment, and from loosely organized volunteers to highly professional career firefighters, the Willimantic Fire Department has provided citizens with skilled, trained, and compassionate service. Through photographs, memorabilia, and stories--the majority of which were collected by the firefighters themselves--Firefighting in Willimantic recognizes the traditions and accomplishments of this outstanding department.
Phase-only Fresnel holograms,' which can be displayed on a single SLM without the need for lenses or complicated optical accessories, substantially simplifies 3-D holographic display systems. Exploring essential concepts, theories, and formulations of these phase-only Fresnel holograms, this book provides comprehensive coverage of modern methods for generating such holograms, which pave the way for commercial products such as compact holographic projectors, heads-up displays, and data security enhancement. Relevant MATLAB codes are provided for readers to implement and evaluate the theories and formulations of different methods, and can be used as a quick start framework for further research and development. This is a crucial and up-to-date treatment of phase-only Fresnel holograms for students and researchers in electrical and electronic engineering, computer science/engineering, applied physics, information technology, and multimedia technology, as well as engineers and scientists in industry developing new products on 3-D displays and holographic projection.
