DIGITAL LASER DISTANCE METER

LD05e-A30-PH67

The Digital Laser Distance Meter
RIEGL
LD05e-A30-PH67
isasuccessor of the LD90-31K-HiP with an
IP67-specified housing.
State-of-the-art digital signal processing enables precise distancemeasurement for complex multi-target
situations even under bad visibility
conditions.
Digitizing the echo signal andsubsequent analyzing allows multitarget distance measurements. Fourtarget distances can be detected andprovided for each laser shot.
The LD05e-A30-PH67 is especially designed for the use without reflectors. It offers extremely“High Penetration”-capabilities under conditions of bad visibility and is therefore ideally suitedfor long-range applications in ship-docking systems and for laser altimetry, etc.
Its High Penetration Mode allows for acquisition of highly accurate and reliable data incomplex target situations, based on a sequence of laser shots and a self-adapting (rather low)
data update rate. Additionally, pre detection-averaging allows significant enhancement of themaximum range.

The following conditions are assumed• target is larger than footprint of laser beam, • perpendicular angle of incidence, • visibility 10 km• typical values for average ambient brightness conditions. In bright sunlight, the operational range is considerably
shorter than under an overcast sky. At dawn or at night the range is even higher.
Reflecting foil 3M DG4090 or equivalent, dimensions ≥ 0.45 x 0.45 m2.
Minimum distance 5 m for full accuracy with retro-reflecting targets.
One sigma standard deviation @ 50 m range under RIEGL test conditions.
Plus distance depending error ≤ ± 20 ppm.
For each laser pulse emitted by the instrument, the echo signal is sampled and digitized. Digitized signals of single laser
shots can be summed to a total signal, thereby increasing the sensitivity and the maximum range at which a target can bemeasured. Summing of single laser shot signals is called pre-detection averaging.
With self-adapting measurement time selected, the effective data update rate depends on the number of targets and theirreflectivity and distance.
