DIGITAL LASER DISTANCE METER

LD05-A80
The RIEGL LD05-A80 is a multi-purpose
laser distance meter based on 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. Digitizing the echo signal
and subsequent analyzing allows multitarget distance measurements. Up to 5
target distances can be detected andprovided for each laser shot.

The digitized waveform data can be logged to either an internal memory card or a TCP/IPdata port. Subsequent offline full wave form analysis allows detailed investigation of thetarget situation, especially with complex target situation
The RIEGL LD05-A80 can be configured for various application modes:•High Penetration and High Accuracy Mode for complex target situations, based ona sequence of laser shot measurements, self-adapting (rather low) data update rate,
significant enhancement of the maximum range based on Pre-Detection-Averaging.

•Fast Mode is between High Speed and High Penetration Mode.

•High Speed Mode for simple target situations, high data update rate.

•••
•
•

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.
Not specified for retroreflectors.
One sigma standard deviation @ 50 m range under RIEGL test conditions.
Plus distance depending error ≤ ± 20 ppm.
With self-adapting measurement time selected, the effective data update rate depends on the number ob targets and theirreflectivity and distance.
