Experimental investigations of light coupling from a core into a ring caused by microbendings in photonic crystal fibres are shown. We present a setup arrangement, mode fields with and without coupling and a plot of power transfer versus localisation of the modulator along the fibre. We also show the most probable explanation of the obtained data.

The paper presents the concept of the interferometric fiber optic sensor system for human psycho-physical activity detection. A fiber optic sensor utilizes phase changes of propagating light to monitor patient's vital signs such as respiration cardiac activity, blood pressure and body's physical movements.

The surveillance system more often uses devices working on different bands that are used not only for detection but also to recognize and identify threats. The paper presents the possibility of protection, detection and identification of risks, achieved through the use of multispectral detection systems in critical infrastructure facilities. The authors consider the benefits of active sensors based on other wavebands, such as millimeter wave radar, terahertz cameras, infrared camera and shows the ability to detect and identify the target using data collected by the sensors. Also discussed the issue of fusion data from different sensors and opportunities that the whole system obtained by application of data fusion.
