The Laser Profile Measuring System LPM-321 provides unprecedented flexibility for long range 3D profiling. Hemispheric scanning, automated or manual operation, reflectorless ranging up to 6000 meters, high accuracy and a comprehensive 3D data acquisition software package operable with any standard laptop or PC are included. Without the use of a retroreflector the LPM-321 calculates the distance to the surface in question, based on the time-of-flight measurement of a short laser pulse. The distance meter comprises state-of-the-art digital signal processing and echo waveform analysis, enabling precise distance measurements even under bad visibility conditions. In multi target situations, the distance meter can provide up to 3 target distances per measurement.

The point of impact of the measuring infrared laser beam can be observed through a telescope. The pan & tilt mount serves to automatically position the beam using the integrated stepper motors with an accuracy of 0.009 degrees. Handwheels for manual operation are provided too.

The optional combination with a calibrated and accurately orientated and mounted high resolution digital camera results in a hybrid sensor system. This system provides data which lends itself to automatic or semi-automatic processing of scan and image data to generate products such as colored pointclouds, textured triangulated surfaces and high resolution panorama images as a basis for, e.g., geotechnical analysis and mining assessment. The LPM series provides the user with the sophistication of RIEGL laser measurement technology combined with a robust and easy to use design.
