According to the present invention, a three-dimensional resolution target is attained together with a relative system for the characterization of the surface defects/indications via indirect visual examinations of various surfaces. The object of such target is to compare and evaluate the resolution of the image acquired from an image acquisition unit.The target comprises incisions and/or projections organized in groups on a surface with three-dimensional geometric shapes that protrude from said surface and/or are embedded in said surface.The system of the present invention is employed for the visual examination characterization and exploits said three-dimensional target. In its basic form, the system comprises an image acquisition unit and at least a memory into which the acquired images are sent and preserved. Other embodiments provide for the use of drones that mount said acquisition unit and which can physically position the target on the surface to be examined.

The invention has as its object a label-shaped device that can be applied to an object to monitor the temperature trend of the object over time. The device comprises:a support substrate;a layer of active material applied to the support, said active material being suitable to provide an optically stimulated response in luminescence (OSL) linked to the temperature/time condition to which the object has been subjected in a given period of time, starting from a dose of electromagnetic radiation initially absorbed having an energy greater than a minimum dependent on the difference between energy levels of the molecular structure of said material active;a layer of semiconductor material coupled to the layer of active material in such a way as to form a heterostructure with the layer of active material so that the luminescence response of the layer of active material is such as to induce a transfer of charges towards the semiconductor material and, therefore, a corresponding modification of the conductivity of the layer of semiconductor material.
