The main aim of the work is the integration of two different fiber-optic sensors: the Michelson interferometric sensor, the Mach-Zehnder interferometric, the Sagnac interferometric and modalmetric sensors. The proposed hybrid sensor is a classical interferometer whose measuring arm is upgraded with modalmetric sensor. The theme of research is to assess the impact of modalmetric sensor to interferometer and comparative assessment of detection capabilities of interferometric sensor, modalmetric sensor and hybrid sensor for different types of excitations. The described tests concern the area of basic researches. The results can be used in the construction sensors with corresponding characteristics and properties to the appropriate applications.

This paper presents the effect of light polarization in a hybrid fiber optic sensor. The hybrid sensor is defined as a combination of interferometer sensor and modalmetric sensor. Hybrid sensor system is based on the effect of outputting interferometric sensor of interference as a result of changes made by the modalmetric system. Balance of polarization in the arms of classical interferometer sensor leads to improvement of contrast of interference pattern at the output of the interferometer. Aim of this study is to present a balance light polarization effects in a hybrid system.

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.

Laser photography device is an imaging device developed in the Institute of Optoelectronics, Military University of Technology and it is an example of modern image acquisition device. The laser photography device allows to define a 3D observation scene thanks to short-time scene illumination and image acquisition method. This device works according to time-spatial framing method. In the paper, basics of time-spatial framing method are explained. Special attention is given to time parameters of device and their influence to spatial parameters of registered images. In this paper the laser photography device and results of chosen experiments are presented and described. Experimental results presented in the paper show the potential and possibilities of using the laser photography device as a camera for observation and measurement applications.

This paper presents infrared sensor for eye tracking system for ophthalmology and truck drivers. System is based on camera and near infrared diode illuminator. We present test results of sensor detection at different operating parameters. Tests were chosen so as to see how the sensor behaves in difficult conditions, additionally tested whether long-term operation of the sensor has an impact on the examined person.
