HONOLULU, May 14, 2007 -- An airborne laser and hyperspectral remote-sensing platform is reinventing the science behind natural resource management decisions and is the most significant new tool since the advent of aerial photography a century ago, said Allan Smith, interim chairman of Hawaii's Department of Land and Natural Resources (DLNR). CAO Lidar: Forest and pasturelands  (Image courtesy Carnegie Airborne Observatory) The system -- the Carnegie Airborne Observatory (CAO) -- combines spectroscopic imaging and waveform laser remote sensing technologies to study regional ecosystems anywhere in the world. The CAO...Read full article

    lidar
    Lidar, short for light detection and ranging, is a remote sensing technology that uses laser light to measure distances and generate precise, three-dimensional information about the shape and characteristics of objects and surfaces. Lidar systems typically consist of a laser scanner, a GPS receiver, and an inertial measurement unit (IMU), all integrated into a single system. Here is how lidar works: Laser emission: A laser emits laser pulses, often in the form of rapid and repetitive laser...
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
