LASER SAFETY

The WINDCUBEv2 is a class 1M Laser product.

CAUTION: The laser beam emitted by WINDCUBEv2 is in the infrared spectrum and is not visible to the naked eye.

CAUTION: Do not stare directly into beam with optical instruments (binoculars or telescopes). The beam is emitted through the Laser aperture situated on the top of the

WINDCUBEv2 at 28° angle off vertical. (Fig. 2).

CAUTION: The WINDCUBEv2 utilizes a class 4 Laser. In order to avoid eye injury, do not open the optical head nor disconnect any optical fibers.

WINDCUBEv2 introduction

The WINDCUBEv2 is a Lidar (Light Detection And Ranging) used for wind profile measure-ment up to 200m.

The Lidar sends infrared laser pulses into the atmosphere. Four beams are sent successively in four cardinal directions along a 28°scanning cone angle. Laser pulses are backscattered by aerosol particles in the air (dust, water droplets, aerosol, etc.), that move at wind speed. The collected backscattered light allows for the calculation of wind speed and direction using Doppler induced laser wavelength shift. Up to 10 different range gates can simulta-neously be measured using the laser pulse time of flight allowing to measure the wind speed at

10 different heights.

The backscattered light is converted into an electronic signal and digitized. A dedicated signal processing algorithm computes wind vector components from four consecutive line of sight measurements. Leosphere Windsoft software controls the hardware and performs the processing. The user interacts with the WINDCUBEv2 (measurement configuration and real-time monitoring) through a graphical user interface, Windweb. Windweb can be dis-played on any web-browser.

Real time and statistical wind data are stored on WINDCUBEv2’s solid-state hard disk drive. The user downloads accumulated data files 1.0

• Before installing your WINDCUBEv2, determine its future location and ensure that:

1. IDENTIFY LOCATION

The system is located away from any obstacles in all wind directions of interest (Fig. 6).

Wind

Obstacles do not interfere with any of the four 28° laser beams (Fig. 7).

Fig. 6 - No obstacle in prevailing wind direction

3.2

In case the ground is soft and/or wet at the site location, it is highly recommended to install the WINDCUBEv2 on a wood palette (or any hard material) to make sure that the system level remains stable over time. A proper and consistent level is vital to main-tain in order to keep the same altitude on both sides of the scanning cone and record accurate data (Fig. 8).

To prevent theft, chain WINDCUBEv2 to one or more ground anchors. Hook a hea-vy duty chain (not included) through WIN-DCUBEv2 ring (Fig. 9).

The anchor should be located below the system so it is less visible to the public. Plan to install hook on chosen spot Difference

 What is CNR?

CNR = Career to Noise Ratio

This value depends on the concentration of aerosols in the atmosphere that backscatter laser light. High atmospheric backscatter coefficient leads to high CNR.

CNR level depends on weather conditions. .

• The four curves should have approximately the same signal level. If one (or more) curves are more than 3dB below the other, it means that an obstacle blocks one (or more) beam.

• Rotate WINDCUBEv2 in order to have all CNR curves superimposed (within a 3dB tolerance margin) and as shown in the good print screen above.
