For years, Riegl Airborne Laser Scanners have been successfully used in powerful unmanned airborne platforms. With the VUX-1UAV airborne scanner and the RiCOPTER which is Riegls’s remotely piloted aircraft system for Unmanned Laser Scanning (ULS), Riegl have revolutionized the commercia...
We have demonstrated the world’s first two-axis scanner using liquid crystal control in which the scanning ranges were 360 degrees in the horizontal direction and 10 degrees in the vertical direction: the beam of a spread angle of 0.3° × 0.8° at minimum sweeps vertically up to 100 ...
[24], trees standing 50 m to 60 m away from the scanner were mapped. An interesting question is what the practical size of the sample plot is for mapping a large area us...Lovell, J.L.; Jupp, D.L.B.; Newnham, G.J.; Culvenor, D.S. Measuring tree stem diameters using ...

The MEMS scanner has the advantages of high operating frequency, low-weight and small volume of package. However, most MEMS scanners have a high operating voltage or high power which makes them incapable of being universally integrated in LiDAR. Efforts have been made to decrease MEMS scanning ...
In an installation shown in Figure 1c, the left side shows two vertically aligned VLP-16s and one horizontally aligned HDL-32E scanner, while the right side shows two vertically aligned VLP-16 scanners. The alignment of the sensors was optimized to cover the largest field of view to capture...

As a result, the beam does not return to the scanner, or the return signal provides inaccurate values. The above-mentioned accuracy limitations of a LiDAR survey occur mainly due to the positioning of the LiDAR platform during laser scanning. The platform position determines the ability of a ...
