Design Principles and Applications. This handbook offers a comprehensive treatment of laser-based remote sensing for lidars light detection and ranging and ladars laser detection and ranging for standoff detection, continuous profiling, and imaging. It highlights practical design with emphasis on hands-on aspects of lidar/ladar architecture, key subsystems, and their critical components. Expert authors discuss various applications, such as in terrestrial and off-shore wind farms, turbulence detectors for airplanes, underwater sensing, greenhouse gas detection, advanced warning for bio/chemical incidents, high-resolution terrain
