This book was released on 1984 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five different instruments were used in coordinated multiple experiments to measure atmospheric turbulence. C sub n squared, the optical refractive structure constant, was measured by thermosondes, UHF radar, stellar scintillometer, and aircraft mounted micro-thermal probes. Presented here are the results of 19 rawinsode flights. Also comparisons of eight thermosonde/radar profiles, one radar, scintillometer, thermosonode profile, and several aircraft profiles are presented. For the scales discussed here, good agreement is shown between radar, thermosonode, and scintillometer data. Worse agreement is obtained from aircraft measurements. A diurnal shift in the C2 profile is noted but no tropopause enhancement is found.

Download or read book Opto Mechanical Systems Design Volume 2 written by Paul Yoder and published by CRC Press. This book was released on 2017-12-19 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 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.
