DIGITAL LASER DISTANCE METER

LD05e-HT
The RIEGL LD05e-HT is a multipurpose laser distance meter basedon precise time-of-flight laser range
measurement.
It uses state-of-the-art digital signal
processing enabling precise distancemeasurement for complex multi-target
situations even under bad visibility
conditions. It is additionally optimized forvery high target temperatures.
Digitizing
theechosignalandsubsequent analyzing allows multi-target
distance measurements. Five target
distances can be detected and provided
for each laser shot.
The LD05e-HT can be configured for various application modes:••

High Penetration Mode for complex target situations, based on a sequence of laser
shots, self-adapting (rather low) data update rateSignificant enhancement of the maximum range based on Pre-Detection-Averaging
Fast Mode with an update rate between High Penetration Mode and High Speedand Mode•••••

Short infrared laser pulses providing excellent interference
immunity
Narrow measurement beam with low divergence for excellent
spatial resolution
Measurement to almost any surface regardless of the angle ofincidence of the beam and the surface characteristics
Lightweight, stable aluminium housing, ready to be used in harshindustrial environments.
Different basic instrument types with pre-configured measurement
modes, but also individually programmable for customer
specific applications

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 3m for full accuracy with reflecting foil
One sigma standard deviation @ 50 m range under RIEGL test conditions.
Accuracy is the degree of conformity of a measured quantity to its actual (true) value.
Plus distance depending error ≤ ± 20 ppm.
Precision, also called reproducibility or repeatability, is the degree to which further measurements show the same result.
With self-adapting measurement time selected, the effective data update rate depends on the number of targets and theirreflectivity and distance.
