Main aims of submitted project are the following: 1. Realization of reticle using diffractive amplitude or phase element for the visible spectrum range. Design of diffractive structures for one or more specific wavelengths and their fabrication by techniques of electron beam lithography. Optical and structural control of fabricated elements. 2. Development and realization of glass mask substrate for replicated production of reticles with sub-micrometer lateral and height dimensions for technique of optical Nanolmprint lithography.

The project addresses the development of hyperspectral camera with high spectral resolution and range of wavelengths 350-1100 nm. On the market are only systems with spectral resolution, which is not suitable for element and molecular analysis, appropriate wavelength range is low. The project aims to develop equipment - hyperspectral camera with high spectral resolution and ability to tune over wavelength lengths in the range 350-1100 nm. This camera is able to provide complex metabolite, pigment and other substances analysis contained in the observed object.

Proposed project is focused on the prediction of neurostimulation methods (vagal nerve stimulation, deep brain stimulation) efficacy in patients with epilepsy. Neurostimulation leads to significant seizure reduction in approximately 50% of implanted patient. By now, we are not able to identify patients who can benefit from implantation of neurostimulator pre-operatively. We managed to develop a statistic mode, which is able to predict efficacy of vagal nerve stimulation based on routine pre-implantation EEG.

The unprecedented accuracy of modern optical clocks has spurred the development of matching frequency comparison techniques, with optical frequency transfer over fibre emerging as the method of choice. However, international time scales, as well as applications outside metrology, require reliable and economically sustainable time transfer in addition to frequency transfer capabilities. This project will advance fibre-based frequency transfer capabilities in Europe towards a universal tool for time and frequency metrology and beyond.

The project aims at the area of optical fibre based sensors, scintillation materials and systems for the detection of ionizing radiation with optical fibres in critical infrastructures. The research will focus on the detection of ionizing radiation in nuclear reactors and particle accelerators, especially in the presence of an extremely high electromagnetic interference. The proposal is intended for remote monitoring in areas with high radiation in order to increase the operational safety.

Advanced document security using diffractive/refractive optical variable image elements generated by laser-based and electron lithography recording methods. Research in and development of methods for combined laser and electron beam master origination, with the aim to impede mimicking of the elements by optical recording techniques. Examiniation of mastering bottlenecks, identification of steps to avoid them.
