Abstract: The present invention concerns a hand holdable writing tool for generating a visual representation on a writable-erasable, passive medium. The invention also provides the assembly of the writing tool and the medium. The writing tool comprises a sensor capable of sensing non-visible light, and a data processing entity, configured for activating and/or disactivating individual inducer entities of the tool, thereby inducing image elements of the medium to generate said visual representation.

Abstract: There is described a dispersive optical device (10) comprising an optically dispersive element (P) with a pair of angled surfaces (pA, pB), namely an upper surface (pA) and a lower surface (pB), positioned along the path of incident light (L) to cause refraction and dispersion of the incident light (L) entering the upper surface (pA) and exiting the lower surface (pB). The dispersive optical device (10) further comprises a mirror element (M) positioned under the lower surface (pB) and angled with respect to the lower surface (pB) to cause dispersed light emerging from the lower surface (pB) to be reflected back towards and through the optically dispersive element (P) to cause further refraction and dispersion of the dispersed light entering the lower surface (pB) and exiting the upper surface (pA). Such dispersive optical device (10) may in particular be used as optical concentrating device for solar energy harvesting.
