Calibration and Image Reconstruction in a Spot Scanning Detection System for Surface Defects
Compared to traditional approaches, the spot scanning surface defect evaluation system (SS-SDES) has better performances on the detection of small defects and defect classification for optical surfaces.

Selective Laser Melting of Maraging Steel Using Synchronized Three-Spot Scanning Strategies. [PDF]
The selective laser melting (SLM) process, a kind of metal additive manufacturing method, can produce parts with complex geometries that cannot be easily manufactured using material removal processes.

In theory, the sharp dose falloff at the distal end of a proton beam allows for high conformal dose to the target. However, conformity has not been fully achieved in practice, primarily due to beam range uncertainty, which is approximately 4% and varies ...

Parallel image scanning with binary phase grating [PDF]
We discuss a novel approach for parallel image scanning, whereby the intensity peaks are generated by a binary phase grating instead of a lens array. These gratings under certain conditions generate one light spot per grating period in several transverse

ON UNIFORMITY OF RASTER ILLUMINATION UNDER LASER SCANNING [PDF]
The paper considers the possibility of a flat light field creation (light raster) of a large size by laser scanning at a distance of several tens of meters with angular sizes equal to 20º×4º.

The SPOT Standard Digital Product Format [PDF]
This document describes the format of the "SPOT scene" digital products which are produced and distributed by SPOT IMAGE. This format is also called the "CAP format", since it has been designed to be produced by the Centre d’Archivage et de ...
