Systems and methods are disclosed for monitoring parameters such as the material properties or structural integrity of a wind turbine blade on a wind turbine. An example method comprises detecting light reflected from a wind turbine blade, generating a value based on the detecting, comparing the value to a threshold value and determining a parameter of the wind turbine blade based on the comparing. A further embodiment comprises determining a wind velocity by detecting reflected light from a target area in front of the wind turbine blade. An example system comprises a detector configured to detect light reflecting from a turbine blade and to produce a value representative of the detected light. The system also comprises a comparator configured to compare the value to a threshold value and to determine a parameter of the turbine blade.

A method of using LIDAR on an airborne vehicle is described. A beam of radiation is transmitted to target areas at least one of above, below, and in front of the airborne vehicle, the target areas including particles or objects. Scattered radiation is received from the target areas. Respective characteristics of the scattered radiation are determined. Air turbulence factor or characteristics are determined from the respective characteristics. The airborne vehicle is controlled based on the air turbulence factor, such that turbulence experienced by the airborne vehicle is minimized. Alternatively, the airborne vehicle is controlled based on the characteristics to avoid colliding with the one or more objects. In another example, the airborne vehicle is controlled based on the characteristics to reduce headwind or increase tailwind, and substantially reduce a carbon footprint of the aircraft.

Systems and methods for laser based measurement of air parameters for use, e.g., on aircraft are disclosed. An example system includes a coherent source of radiation, a modulator, a transceiver, an optical mixer, and a measuring system. The coherent source produces a coherent radiation beam, and the modulator is configured to modulate the coherent radiation beam. The transceiver is configured to transmit the modulated radiation beam to, and receive a scattered radiation signal from a target region. The optical mixer is configured to determine a difference between the scattered radiation signal and the reference radiation beam. The measuring system is configured to determine at least one of velocity, air density, pressure, temperature, barometric altitude, angle of attack, angle of side slip, icing and turbulence based on the difference between the scattered radiation signal and the reference radiation beam.

A wind turbine power management system and method includes one or more wind turbines at a wind farm and one or more laser sources used to measure wind conditions remote from the wind farm. The laser sources may be collocated with the wind turbines, and are able to measure wind conditions at various predetermined ranges from the wind turbines. The laser sources measure wind conditions at locations that provide 10 to 20 seconds of advance notice, and also at locations that provide 50 to 100 seconds of advance notice. Wind condition at locations that provide 500 or more seconds of advance notice are also measured using remote laser sources.

An all fiber optic laser based scanning system for real time terrain mapping under degraded visual conditions is disclosed. A laser output is modulated to achieve a desired pulse width and pulse repetition frequency (PRF) and the modulated signal is amplified. The amplified optical signals are split into N channels that correspond to N elements of an optically phased array that steers light by modulating the phase of light entering and exiting the optical system. By applying a linear phase shift across the beam's wave front, the light propagating along the system's optical axis is steered to an off-axis angle. A real time map of an underlying terrain is accomplished by sweeping the N channel array across the terrain while collecting range information from each scan grid.

Systems and methods for laser based measurement of air parameters are disclosed. An example system includes a source of radiation, an amplification system with one or more power amplification stages, a transceiver, and an optical mixer. The source produces a plurality of beams, and the amplification system is configured to amplify the beams. The transceiver is configured to transmit the modulated beam to, and receive a scattered beam from a target region. The optical mixer is configured to determine a difference between the scattered beam and a reference beam, which is used to determine a Doppler shift therefrom. In certain embodiments, the amplification system includes a fiber preamplifier and one or more fiber power amplifiers stages.

Methods and systems for collecting high-density wind velocity data for the inflow area of a wind turbine are presented. Wind turbines are provided with one or more wind velocity sensors that provide a plurality of wind velocity measurements to the turbine from various ranges and locations across the inflow. Sensors are proximate to the wind turbine. Sensors mounted on the turbine's nacelle work collaboratively to provide the wind velocity measurements. Sensors mounted on the turbine's hub spin with the turbine blades. Spatial and temporal wind mapping provides improved fidelity of data to the wind turbine control system.
