Modeling and Calibration of a Novel One-Mirror Galvanometric Laser Scanner [PDF]
Sensors, 2017 A laser stripe sensor has limited application when a point cloud of geometric samples on the surface of the object needs to be collected, so a galvanometric laser scanner is designed by using a one-mirror galvanometer element as its mechanical device to ...

Calibration and characteristics of an electrowetting laser scanner. [PDF]
IEEE Sens J, 2020 We present a calibration method to correct for fabrication variations and optical misalignment in a two-dimensional electrowetting scanner. These scanners are an attractive option due to being transmissive, nonmechanical, having a large scan angle (±13.7°), and low power consumption (μW).

Optimising Mobile Mapping System Laser Scanner Orientation
ISPRS International Journal of Geo-Information, 2015 Multiple laser scanner hardware configurations can be applied to Mobile Mapping Systems. As best practice, laser scanners are rotated horizontally or inclined vertically to increase the probability of contact between the laser scan plane and any surfaces

3D Laser Scanner for Underwater Manipulation. [PDF]
Sensors (Basel), 2018 Nowadays, research in autonomous underwater manipulation has demonstrated simple applications like picking an object from the sea floor, turning a valve or plugging and unplugging a connector. These are fairly simple tasks compared with those already demonstrated by the mobile robotics community, which include, among others, safe arm motion within ...

Interferometric Laser Scanner for Direction Determination. [PDF]
Sensors (Basel), 2016 In this paper, we explore the potential capabilities of new laser scanning-based method for direction determination. The method for fully coherent beams is extended to the case when interference pattern is produced in the turbulent atmosphere by two partially coherent sources.
