Book Description
Laser remote sensing is a powerful technique with a wide range of applications in fields as diverse as atmospheric studies, marine ecology, space exploration, air travel safety and military target identification, thus addressing societal needs. Many LIDAR (Light Detection and Ranging) instruments have been developed, from ground-based, airborne and space-based platforms. However, significant improvements (more durable, lightweight, economical) are required in materials used for the LIDAR instrumentation system. This book, first published in 2005, reviews and outlines trends and challenges in this important field. Contributions from key research institutions show that advanced devices developed by the telecommunication industry can play an important role in addressing the increasing demand for more efficient and compact LIDAR systems. Fiber optics lasers and MEMS-based semiconductor lasers are examples of such devices. Reliability of LIDAR instruments is also addressed. Indeed, for LIDAR instruments operating in space, the reliability and lifetime of laser diodes are particularly critical.

Book Description
The Workshop on Tunable Solid State Lasers for Remote Sensing was held at Stanford University in October 1984 to assess the state of the art in tunable solid state lasers for remote sensing from satellite platforms. The value of conducting global remote sensing measurements of atmospheric chemistry, climate, and weather in the 1990s is now established. What is not yet defined, however, is the status of the developing tunable laser technology that must meet both the scientific requirements and the space platform constraints. This workshop was convened by the Office of Aeronautics and Space Technology (OAST) of the National Aeronautics and Space Administration (NASA) to assess the status and progress in tunable solid state laser sources for remote sensing. The workshop was organized to facilitate information exchange across a number of technologies from remote sensing requirements to crystal growth of the materials important for the development of the tunable laser sources. The emphasis was on the recent developments in tunable solid state laser sources necessary to meet the future transmitter requirements for global remote sensing. A goal of the workshop was to form recommendations to NASA on the current and future prospects for solid state laser technology that will allow remote sensing measurements from air, shuttle, and free-flying satellite platforms. The emphasis was on solid state laser sources because they offer the best potential for meeting the demanding requirements of compact size, good efficiency, and long operational lifetimes required for future space station and free-flying platform operation.

Book Description
Methods and Materials for Remote Sensing: Infrared Photo-Detectors, Radiometers and Arrays presents the basic principles and the guidelines for the design of IR and microwave radiometers intended for the detection of weak electromagnetic signals in a noisy background. Significant attention is paid in this book to the discussion of the origin of the noises and consideration of the physical factors limiting the sensitivity of photo sensors. The physico-chemical properties of narrow-band semiconductors, which are the basic photosensitive materials for the microwave and IR radiometry, are discussed. Also described are the methods for growing the single crystals, epitaxial films and arrays from solid solutions of these compounds for the application in photosensitive detectors. The main goal of Methods and Materials for Remote Sensing: Infrared Photo-Detectors, Radiometers and Arrays is to present the entire material from the unifying physical viewpoint, which will be helpful for the designers of photo-detecting devices, and professionals contributing in various areas of remote sensing.

Book Description
The field of optical and laser remote sensing has grown rapidly in recent years. This dynamic growth has been stimulated not only by technological advances in lasers, detectors, and optical system design, but also by the potential application of remote sensing systems to a wide variety of atmo spheric measurements. Optical and laser remote sensing can allow single ended measurement capability not offered by conventional point-detection techniques. While many past measurements have been associated with labo ratory research. practical systems have recently been developed which are capable of remotely detecting. measuring. and tracking a wide range of molecular and atomic species in the atmosphere with concentrations of parts per billion and at ranges over 100 km. This book is a compilation of papers which represent an overview of the present state of development of optical and laser remote sensing tech nology. The subjects covered include both passive and active remote sen sing techniques in the UV, visible, and IR spectral regions. related laser and detector technology, and atmospheric propagation and system analysis considerations. While the papers do not constitute an exhaustive treat ment of the excellent research being conducted in this field, they are representative of the wide diversity of present efforts. It is hoped that the reader will gain a general understanding of the current research in optical and laser remote sensing as well as an overview of current systems development.

Book Description
This is the final report of a three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory. Remote measurement of wind velocities is critical to a wide variety of applications such as environmental studies, weather prediction, aircraft safety, the accuracy of projectiles, bombs, parachute drops, prediction of the dispersal of chemical and biological warfare agents, and the debris from nuclear explosions. Major programs to develop remote sensors for these applications currently exist in the DoD and NASA. At present, however, there are no real-time, three-dimensional wind measurement techniques that are practical for many of these applications and we report on two new promising techniques. The first new technique uses an elastic backscatter lidar to track aerosol patterns in the atmosphere and to calculate three dimensional wind velocities from changes in the positions of the aerosol patterns. This was first done by Professor Ed Eloranta of the University of Wisconsin using post processing techniques and we are adapting Professor Eloranta's algorithms to a real-time data processor and installing it in an existing elastic backscatter lidar system at Los Alamos (the XM94 helicopter lidar), which has a compatible data processing and control system. The second novel wind sensing technique is based on radio-frequency (RF) modulation and spatial filtering of elastic backscatter lidars. Because of their compactness and reliability, solid state lasers are the lasers of choice for many remote sensing applications, including wind sensing.
