Abstract The design of integrated sealand airborne laser scanner is proposed.In order to collect simultaneous land and waterdepth measurements，high frequency dual wavelength laser and large dynamic optical receiver are used.The system uses self calibrating timetodigital converter to rebuild the high precise point cloud data.The modulation and demodulation techniques based on coded orthogonal frequency division multiplexing are used to transmit airborne point cloud data back to ground stations.
Key words ：
airborne laser scanner
dual wavelength
time-to-digital converter
coded orthogonal frequency division multiplexing
point cloud data
