The calibrated amplitude (intensity) reading
Traditionally scanners provided amplitude readings for measurements as numbers, without specifying the physical meaning of the number. The VZ-400 provides an amplitude for every target echo. The amplitude is actually defined as a ratio of the actual detected optical amplitude of the echo pulse versus detection threshold.
For the first time, the “calibrated reflectivity” capability
The V-Line introduces some measurement of the laser radar cross-section by providing a so called reflectivity value for each target echo. The reflectivity value gives the ratio of the actual optical amplitude versus the optical amplitude of a diffuse white target at the same range.
In a visual representation, where each point of a point cloud has assigned a brightness according to the reflectivity, objects with the same reflectivity have the same brightness regardless of the distance to the scanner. This gives a natural impression and increases potential for object recognition.
Time-optimized fine-scans
The program “reflector scan” with 300KHz pulse repetition rate and low laser output opens the doors to flat, eye-safe scanning of retro reflectors for registration purposes.
The VZ-400 automatically selects the best suited measurement program for performing a reflector scan. Usually, this will be the “reflector scan” program for targets made from retro-reflective material in the range of up to 150 m to minimize acquisition time.
The superior ranging precision
The VZ-400 shows high precision, due to low noise. Exceptional results are observed even in critical measurement situations.
Details on the multiple target capacity
The VZ-400 provides up to 3 targets in the “high speed” program and up to 9 targets in the “long range” program.
There is a lot more information where this came from. Once again, if you want to know, just ask.
