چکیده
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 study, and as for the museum’s conservators to obtain the preliminary often essential information for preservation and restoration of damaged or degraded objects and to assess the authenticity of artefacts and paintings in many cases. On the other side, availability of a portable apparatus represents a strong constraint for many analyses to be performed in situ, since objects of large dimensions or particularly fragile cannot be easily and/or safely transferred to specific laboratories. The infrared and ultraviolet spectrometry is then a suitable technology for this kind of analysis. Moreover, a portable Compton spectrometer has been developed and applied to investigation of paintings, thus complementing usual IR and UV analyses. In this contribution, a multipurpose multispectral digital system is presented, ranging from infrared radiation to visible light, ultraviolet fluorescence and gammaand X-ray spectroscopy, in order to perform suitable analyses of paintings on wood or canvas, preliminary to any restoration or cleaning.

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.

The recent developments of our method to design two freeform optical surfaces (either refractive or reflective) using an optimized ray mapping computation are presented. The procedure is based on the Monge-Kantorovich theory of optimal mass transport, and the related conditions for an optimal mapping. The procedure is illustrated by designing an efficient street lighting lens, achieving an opti...

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...

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 ...
