This book details the lives of two married geniuses, Aden and Marjorie Meinel, who helped to pioneer modern optics and solar energy in the U.S. Aden B. Meinel and Marjorie P. Meinel stood at the confluence of several overarching technological developments during their lifetimes, including postwar aerial surveillance by spy planes and satellites, solar energy, the evolution of telescope design, interdisciplinary optics, and photonics. Yet, their incredible stories and their long list of scientific contributions have never been adequately recognized in one place. In this book, James Breckinridge and Alec M. Pridgeon correct this oversight by sharing the story of this powerful duo. The book follows their lives and covers large scientific developments between World War II to the Cold War. James B. Breckinridge, a previous advisee and later colleague to the Meinels, and historian and scientist Alec M. Pridgeon collected more than 200 hours of oral interviews with those who worked closely with the Meinels and some who built their careers around the findings made possible by their work. The book shares and analyzes the work done by the Meinels, and it also includes incredible insights from an unpublished Meinel autobiography.

This history of SAFSP is dedicated to all those men and women who fought the Cold War, in silence - from above. No organization is better at gathering overhead intelligence than the U.S. National Reconnaissance Office (NRO). Today's NRO grew out of 3 organizations: AF, CIA, and Navy. The AF office for satellite reconnaissance was called the Secretary of Air Force's Office of Special Projects [SAFSP]. This monograph describes the birth of Air Force satellite reconnaissance. When SAFSP was created in response to Presidential recognition of a national imperative, 4 tenets captured the sense of urgency: direct access to national leadership, covert management/operations, highest national priority, and rapid procurement. In addition, 3 management principles led to SAFSP's success over 30+ years of providing reconnaissance intelligence: strong dedication to mission, empowerment at all levels, and reporting by exception.

The United States developed the Gambit and Hexagon programs to improve the nation's means for peering over the iron curtain that separated western democracies from east European and Asian communist countries. The inability to gain insight into vast "denied areas" required exceptional systems to understand threats posed by US adversaries. Corona was the first imagery satellite system to help see into those areas. Hexagon began as a Central Intelligence Agency (CIA) program with the first concepts proposed in 1964. The CIA's primary goal was to develop an imagery system with Corona-like ability to image wide swaths of the earth, but with resolution equivalent to Gambit. Such a system would afford the United States even greater advantages monitoring the arms race that had developed with the nation's adversaries. The Hexagon mapping camera flew on 12 of the 20 Hexagon missions. It proved to be a remarkably efficient and prodigious producer of imagery for mapping purposes. The mapping camera system was successful by every standard including technical capabilities, reliability, and capacity.

Opto-Mechanical Systems Design, Fourth Edition is different in many ways from its three earlier editions: coauthor Daniel Vukobratovich has brought his broad expertise in materials, opto-mechanical design, analysis of optical instruments, large mirrors, and structures to bear throughout the book; Jan Nijenhuis has contributed a comprehensive new chapter on kinematics and applications of flexures; and several other experts in special aspects of opto-mechanics have contributed portions of other chapters. An expanded feature—a total of 110 worked-out design examples—has been added to several chapters to show how the theory, equations, and analytical methods can be applied by the reader. Finally, the extended text, new illustrations, new tables of data, and new references have warranted publication of this work in the form of two separate but closely entwined volumes. This first volume, Design and Analysis of Opto-Mechanical Assemblies, addresses topics pertaining primarily to optics smaller than 50 cm aperture. It summarizes the opto-mechanical design process, considers pertinent environmental influences, lists and updates key parameters for materials, illustrates numerous ways for mounting individual and multiple lenses, shows typical ways to design and mount windows and similar components, details designs for many types of prisms and techniques for mounting them, suggests designs and mounting techniques for small mirrors, explains the benefits of kinematic design and uses of flexures, describes how to analyze various types of opto-mechanical interfaces, demonstrates how the strength of glass can be determined and how to estimate stress generated in optics, and explains how changing temperature affects opto-mechanical assemblies.

The second volume, Design and Analysis of Large Mirrors and Structures, concentrates on the design and mounting of significantly larger optics and their structures, including a new and important topic: detailed consideration of factors affecting large mirror performance. The book details how to design and fabricate very large single-substrate, segmented, and lightweight mirrors; describes mountings for large mirrors with their optical axes in vertical, horizontal, and variable orientations; indicates how metal and composite mirrors differ from ones made of glass; explains key design aspects of optical instrument structural design; and takes a look at an emerging technology—the evolution and applications of silicon and silicon carbide in mirrors and other types of components for optical applications.
