Abstract: An airborne super-continuum 50-band hyperspectral light detection and ranging system comprises an integrated control system, a storage unit, a super-continuum laser system, an optical transmitting system, a reflecting mirror, a scanning system, an optical receiving system, a super-continuum hyperspectral laser detection system, a plane array CCD camera. The operation process includes super-continuum laser system emitting continuous hyperspectral pulsed lasers, performing lasers beam expansion and collimation, emitting it to ground objects, reflecting it, receiving it by the scanning system, transmitting to the optical receiving system, and focusing it into hyperspectral laser detection system for outputting laser hyperspectrum and 3D spatial data, storing laser data in the storage unit with high-resolution multi-spectral data. The system acquires hyperspectral spectrum data with 50 bands at aspectral range of 400-900 nm, spectral resolution of 10 nm and 3D spatial data of ground objects with a ground resolution better than 0.5 meters.
