The authors have designed this timely new book in response to the need for up-to-date and complete coverage of multi-disciplinary basic principles of optical beam control for imaging satellites and laser systems. As the uses of imaging satellites and laser systems increase, optical beam control for these systems will occupy engineers and scientists for years to come. The book introduces space telescopes, ground telescopes, laser communications, and high energy laser systems, covering light sources, lenses, wave optics, diffraction, and polarization, as well as fine pointing control, classical control, modern control, Kalman filters, sensors, actuators, flexible control, slew maneuvers, and acquisition, tracking, and pointing. The authors have over 30 years' experience in research, development, and testing of complex state-of-art systems, such as 3-meter diameter segmented mirror space telescopes and high energy laser beam control systems. As a text and reference dealing with basics of optical beam control, this book includes information on: Sources of aberrations, vibration and jitter, optical aberrations, air turbulence, and measure of optical aberrations Vibration isolation and jitter control, active jitter control, strap down, and inertial stable platform Adaptive optics, wavefront sensors, wavefront reconstruction, adaptive optics configurations, and control systems Imaging satellites, telescope design, optical train components, image aberration, and performance analysis Laser beam control hardware, laser aberration, and laser performance analysis Optical Beam Control is an essential reference for engineers working in imaging satellites and laser systems along with electrical engineers focused on optics, satellites, lasers, and control systems. The text is also valuable for students taking courses on laser technology, satellite control, spacecraft design, and optics and photonics.

This book was written to help college students understand physics without complicated math. Each year thousands of college students pursuing business and humanities degrees find themselves taking a course in introductory physics. But many will have serious trouble solving physics problems because they do not have enough experience using mathematical equations. Understanding physics is challenging without a strong math background, but not impossible. Unlike other introductions to physics, this book explains the basic concepts in classical mechanics with a minimal amount mathematical expressions so new students can spend their time learning physics, not math. The result is not only a better understanding of physics, but possibly a better grade. This study guide covers the three aspects of classical mechanics: basics of motion, rules for gravitational interaction among two or more objects, and rotational motion. The bottom line is that this book was written to help students better understand the mathematical parts of undergraduate classical mechanics so they can concentrate on learning physics, not math.
