Abstract
Laser scanners have emerged as powerful instrument for high-precision 3D geometry measurement and high-resolution reverse engineering in combination with 3D printers etc. However, such attractive laser scanners have failed to address to fading phenomenon, which was a critical issue of laser scanning systems. Although extensive research has been carried out on the fading issue, no single study exists which effectively coped with such an impairment inherent in 3D geometry measurement using laser scanners. In this article, we propose a 3D laser scanner having a tunable high-speed polarization scrambling scheme and cope with the fading phenomenon. To our knowledge, this is the first report of versatile removal of the fading phenomenon inherent in laser scanning systems
