Field performance of an all-semiconductor laser coherent Doppler lidar.
We implement and test what, to our knowledge, is the first deployable coherent Doppler lidar (CDL) system based on a compact, inexpensive all-semiconductor laser (SL). To demonstrate the field performance of our SL-CDL remote sensor, we compare a 36 h time series of averaged radial wind speeds measured by our instrument at an 80 m distance to those simultaneously obtained from an industry-stand...
متن کاملAn all-fiber image-reject homodyne coherent Doppler wind lidar.
In this paper, we present an alternative approach to the down-conversion (translation) of the received optical signals collected by the antenna of an all-fiber coherent Doppler lidar (CDL). The proposed method, widely known as image-reject, quadrature detection, or in-phase/quadrature-phase detection, utilizes the advances in fiber optic communications such that the received signal can be optic...
متن کاملDevelopment of All-fiber coherent Doppler LIDAR system for wind sensing
Coherent Doppler LIDAR is being utilized to develop a mobile wind speed measuring station. We are building an all fiber based eye safe laser system to measure wind speed in urban areas. A 1.5μ.m polarization maintained fiber optics master oscillator power amplifier system is used, which utilizes inexpensive telecommunication components. A heterodyne balanced detection is being used to suppress ...
متن کاملA reconfigurable all-fiber polarization-diversity coherent Doppler lidar: principles and numerical simulations.
This paper shows an efficient adaptation of a polarization diversity optical front-end, commonly used in high-speed fiber-optic communications, in a coherent Doppler lidar (CDL). The adopted architecture can be employed in a modified transceiver design for an all-fiber micropulsed coherent Doppler wind lidar where the performance limits of such systems are pushed beyond the conventionally avail...
متن کاملWind velocity estimate and signal to noise ratio analysis of an all fiber coherent Doppler Lidar system
In CDL, a laser pulse is transmitted into the atmosphere and the Doppler shifted signal that scatters off of atmospheric aerosol particles is detected by beating this signal with a local oscillator (LO) [1][2][3] . The resulting RF signal has a Doppler shift proportional to the speed of aerosol particles along the line of sight of the laser beam. In this paper, we present preliminary results fr...
