Abstract: Die Erfindung betrifft eine optische Anordnung (20) zur Umwandlung eines Eingangslaserstrahls (18) in einen linienartigen Ausgangsstrahl (12), die optische Anordnung umfassend eine Umformoptik (24) aufweisend eine Eingangsapertur, durch welche der Eingangsla- serstrahl einstrahlbar ist, und eine länglich ausgebildete Ausgangsapertur, wobei die Umformoptik derart ausgebildet ist, dass der durch die Eingangsapertur eingestrahlte Eingangslaserstrahl in ein durch die Ausgangsapertur austretendes Strahlpaket mit einer Vielzahl von Strahlsegmenten umgewandelt wird, die optische Anordnung ferner umfassend eine Homogenisierungsoptik (28), welche dazu ausgebildet ist, das Strahlpaket in den linienartigen Ausgangsstrahl umzuwandeln, wobei verschiedene Strahlsegmente des Strahlpakets entlang der Linienrichtung durchmischt und überlagert werden, wobei eine Umlenkoptik (22) vorgesehen ist, welche dazu ausgebildet ist, den Eingangslaserstrahl derart umzulenken, dass eine Einstrahlposition und/oder eine Einstrahlrichtung des Eingangslaserstrahls an der Eingangsapertur der Umformoptik zeitabhängig verändert wird. Die Erfindung betrifft auch ein Lasersystem (10) zur Erzeugung einer linienförmigen Intensitätsverteilung.

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.

Abstract: A multi-function imaging system (1) comprises a light sensor (41) and a software defined light source to enable real-time automatic adjustment of various parameters of the one or more light sources (11; 15, 16, 17). The system is realized in a single unit, or as multiple co-located units, thus reducing the cost of having such multiple functions. The system is capable of self-calibrating in the field to enable accurate imaging.

Abstract: Systems, devices, and techniques for creating blind annular vias for metallized vias are described. For example, a vortex beam may be applied to an optically transmissive substrate, where the vortex beam may modify a portion of the substrate in an annular shape. The annular shape may extend from a surface of the substrate to a depth that is less than a thickness of the substrate, and the annular shape may have an annular width (e.g., a ring width) that is the same for various diameters of the annular shape. A blind annular via may be formed by etching the modified portion of the substrate, where the blind annular via may include a pillar comprising the same material as the surrounding substrate. In addition, a metallized annular via may be created by filling the blind annular via with a conductive material, and removing a portion of the substrate opposite the surface.

Abstract: The system and method for combining two optical assemblies into the same volume, particularly when the field of view of the two assemblies are different, so that the overall volume and swap for the system is reduced. This also allows both subsystems to use the same external protective window, reducing overall cost for a system of co-located dissimilar optical systems in a single aperture.
