The performance of discrete-Fourier-transform (DFT)-based velocity estimators for wind-sensing coherent Doppler lidar systems in the Kolmogorov turbulence regime is summarized using Monte Carlo simulations. Furthermore, a signal model, a simulation p

We have proposed and studied a fiber-based Doppler lidar for airborne turbulence sensor. A lidar with small size, high reliability, and high flexibility of arrangement could be achieved by combining fiber-based optics, which are commercially availabl

We propose a new detection method for a pseudo-random frequency modulation continuous wave (RM-CW) coherent lidar. The feature of this method is modulation of local beam with a time delayed pseudo-random sequence. Heterodyne detection and correlation

We have developed a 1.5-μm eye-safe wavelength high average power laser amplifier using an Er,Yb:glass planar waveguide for coherent Doppler LIDAR. Large cooling surface of the planar waveguide enabled high average power pumping for Er,Yb:glass whic

We have developed a 1.5-μm high-power laser amplifier using Er, Yb:glass planar waveguide for a coherent Doppler LIDAR. Large cooling surface of the waveguide realized highaverage power pumping for Er, Yb:glass which has low thermal fracture limit.
