| | Combined range laser scanner - Patent 5420411 |
| | One preferred embodiment comprises two laser optical illumination systems, a first system optimized for contact operation, and a second system optimized for longer distance scanning, and the two laser scanning systems are integrated into one combined range laser scanner. | | | The second laser illumination system is optimized for longer range scanning from approximately two to seventeen feet, and the two laser scanning systems are integrated into one combined range laser scanner. | | | In the short range laser diode assembly, the lens 78 focuses the laser beam for short range scanning operations, whereas in the longer range laser diode assembly, the lens 78 focuses the laser beam for longer range scanning operation. |

| | A Paint-Brush Laser Range Scanner |
| | A laser range scanner is being developed that can acquire different-view images of an object and combine the images without image registration. | | | By appropriately adjusting the speed at which the laser is swept over the object, the user can capture dense data in areas where high details are required and sparse data in areas where coarse data are sufficient. | | | Range data obtained when scanning the object from the left. |

| | Resume of Guoling Shen |
| | Large workspace means that the viewing volume of the system is large compared to the field of view of the scanner, and the driving devices have more degrees of freedom to position the laser scanner and/or the object. | | | With the use of robots and the development of software, it is also possible to automate the measuring process. | | | The ultimate objective of this project is to develop an automated surface acquisition and reconstruction system for complex objects in a large workspace, using laser range scanner. |

| | A Scalable Multi-User Laser Input System |
| | Maximizing scanner accuracy while minimizing engineering costs is a key challenge to future scanner designs. | | | We propose a new range scanner design, specifically chosen to minimize calibration complexity and cost. | | | Since it is difficult to ensure absolute repeatability of moving parts, a design with only statically arranged components can dramatically reduce the costs associated with calibration. |
