Minimally invasive surgery has for many applications replaced open surgery, since the amount of tissue, which has to be cut, is reduced to a minimum, resulting in a quicker recovery of the patient connected with reduced post operational stress. But minimally invasive surgery has restricted the working environment of the surgeon due to the loss of two mayor human senses, three dimensional vision...

The application of multispectral nondestructive techniques initially developed in the field of materials science to art and archaeological objects provides the art historian or the archaeologist reliable qualitative and often quantitative information. By this way, it is possible to understand, for instance, the technical and intellectual know-how of the artists or craftsmen of the period under ...

Hybrid optical elements that combine refractive and diffractive functionality are versatile components for all kinds of applications in imaging or metrology. In the past those elements were composed of a flat diffractive and a curved refractive surface. Fusing both functions in a single surface will enhance the capabilities of these optical components further. The fabrication of such precision ...

Illuminators are essential parts for active THz imaging systems and consist of a source and a beam shaper to efficiently distribute the source power across the FOV and evenly light the object plane. Significant R&D has been spent on designs for ‘Gaussian-to-tophat beam shapers’ (GTBS) [2] with applications in the visible and THz range [3]. Here we report on the first refractive operating THz GTBS.
