This paper briefly discusses the mobile ground-based incoherent Doppler wind lidar system, with iodine filters as receiving frequency discriminators, developed by the Ocean Remote Sensing Laboratory, Ocean University of Qingdao, China. The presented result of wind profiles in October and November 2000, retrieved from the combined Mie and Rayleigh backscattering, is the first report to our knowledge of wind measurements in the troposphere by such a system, where the required independent measurement of aerosol-scattering ratio can also be performed. A second iodine vapor filter was used to lock the laser to absolute frequency reference for both wind and aerosol-scattering ratio measurements. Intercomparison experiments of the lidar wind profile measurements were performed with pilot balloons. Results showed that the standard deviation of wind speed and wind direction, for the 2-4 km altitude range, were 0.985m/s and 17.9

A new incoherent lidar for measuring atmospheric wind using an iodine molecular filter as the frequency discriminator is proposed. A unique feature of the proposed lidar lies in its capability for simultaneous measurement of aerosol mixing ratio, with which the radial wind can be determined uniquely from the lidar return. A preliminary laboratory experiment using a monolithic cw diode-pumped frequency-doubled YAG laser at 532nm and a rotating wheel has been performed. The result of this laboratory experiment have not only demonstrated the feasibility of the proposed wind measurement technique but also determined an intrinsic lidar measurement uncertainty of 12cm/s for a measurement time of 5min.

A new method of solving the important problem in ocean optics-the radiative transfer is presented. This method is different from that of tra.ditional ocean optics. We initiate tile transform radiative transfer model as well as concept, theory and research method of information transmission and apply them to the study of radiative transfer in the ocean to overcome difficulties in solving tile integro-differential equation of radiative transfer. By using the optical information processing and linear system theory, the optical transfer fuuetion of the sea water body concerning the image transmission in water, the narrrow-light beam transmission with relation to the ocean lidar, the inverse problem of radiative transfer related to ocean optical remote sensing, the characteristic distribution of the light field in deep sea, etc. have been concisely solevd. Meanwhile, we propose the method of optical informntion processing for the experimental measurement in ocean optics. As a result, the measurement of small-angle (0.05
