OPTICAL BEAM CONTROLImaging Satellites and Laser Systems 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 aberrationsVibration isolation and jitter control, active jitter control, strap down, and inertial stable platformAdaptive optics, wavefront sensors, wavefront reconstruction, adaptive optics configurations, and control systemsImaging satellites, telescope design, optical train components, image aberration, and performance analysisLaser beam control hardware, laser aberration, and laser performance analysisOptical 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.
