RANGE
• Maximum
The maximum range directly depends on the pulse length, on the power ofthe laser and on the weather conditions. Maximum height is reached at 200 meters for a 20 meter long pulse, under certain conditions (hazeand clear conditions).
• Minimum
The minimum range depends on the pulse length. For a distance below 40meters, the light pulse has not totally quit the emitter; thus the light reflected by the optics is much more intense than the light backscattered by the aerosols. The minimum range is 40 meters for a 20 meter long pulse.
DATA OUTPUT FREQUENCY
The sequential scan of a line of sight and the associated data transfertakes 500 ms. The 90° rotation time to scan another line of sight is 500 ms. Therefore, the data output frequency is 1 Hz (1 s to get radialwind speed along the line of sight).
