Non-invasive optical diagnostic methods allow important information about studied systems to be obtained in a non-destructive way. Complete diagnosis requires information about the chemical composition as well as the morphological structure of a sample. We report on the development of an opto-mechanical probe that combines Raman spectroscopy (RS) a...

The paper deals with the experimental analysis focused on the determination of strain in wooden building structures using optical fibers with FBG sensors. Firstly, optical fibers were used to measure displacements of layers and surface strain of the lower surface of the ceiling panels made from mechanically jointed cross laminated timber (CLT). The...

Within the EU project i-Protect fibre optic sensors for measuring heart rate, respiratory rate and skin temperature are being developed. The plastic optical fibre (POF) sensors are based on macrobending effects, photoplethysmography and fluorescence thermometry. The sensors and monitoring units are integrated into underwear and are communicating wi...

This paper reports about the EU project i-Protect in which fibre optic sensors for measuring heart rate, respiratory rate and skin temperature are being developed. The sensors and monitoring units are integrated into underwear and are communicating wireless via body area network and communication unit with the rescue command centre. All sensors can...

Within the EU FP6 project OFSETH different types of fiber optic sensor for monitoring of respiratory movement were investigated [5]-[9]. These sensors were based on macrobending effects, fiber Bragg gratings, long period gratings in microstructured polymer fiber and optical timedomain reflectometry in POF. Based on the knowledge of OFSETH a new set...
