In this work, we investigate the distribution characteristics of the point cloud in dual wedge scanning and propose a sub-pixel scanning-based 3D reconstruction and image processing method for point cloud.
The aim of this project is to build a small scanning device with an overall size that is approximately 4mm in diameter by 4mm in length with the use of a dual-wedge scanning system consisting of an angle
For a scanner consisting of a rotating polygon and a galvanometric scanner, two relay telescopes are normally used. We have developed a dual-wedge scanner which has the potential to perform the
By building a mathematical model of an ideal dual-wedge scanning trajectory and a trajectory affected by mechanical errors, this paper analyzes the types and degree of influence on
a dual-wedge scanner re-placing the raster scanner. The optical path begins at the 830 nm linearly polarized laser diode with a 4.5 mm beam diameter and passes throu
This paper explores the use of a pair of optical wedges as a scanning head and reports initial development of an exper- imental system. Like the Dove prism SLDV, this dual wedge SLDV would
