A Framework for Adaptive Width Control of Dense Contour-Parallel Toolpaths in Fused Deposition Modeling

3D printing techniques such as Fused Deposition Modeling (FDM) have enabled the fabrication of complex geometry quickly and cheaply. Objects are produced by filling (a portion of) the 2D polygons of consecutive layers with contour-parallel extrusion toolpaths. Uniform width toolpaths consisting of inward offsets from the outline polygons...

CAESAR, a CCD airborne experimental scanner for applications in remote sensing radiometric and geometric calibration

Within the framework of the National Remote Sensing Programme, an airborne push-broom scanner was developed in The Netherlands by the National Aerospace Laboratory NLR and the Institute for Applied Physics TNO-TH (TPD). With the development of this scanner, named CAESAR, two objectives were fulfilled: technical knowledge about CCD detectors and...
