Abstract
A system and method for measuring wind velocities are provided. A laser wind velocimeter with a radiation source includes a fiber laser. All optical signals, transmitted and received, are conveyed by optical fibers. An amplifier amplifies a source laser, which is then transmitted to one or more transceivers. The one or more transceivers, each projecting along a different axis, and each with a single optical fiber input/output interface act as both the transmission device to focus the radiation at a target region, and as the receiving system for collecting reflected radiation. The one or more transceivers transmit radiation to the target region. A portion of the reflected radiation collected by the receiving system is analyzed to determine the Doppler shift, which can me used to measure wind velocity
