Summary:An innovative polarization state sensor is presented for the determination of the distribution of polarization state of light reflected from the different objects. Such a sensor based on only one integral polarization-holographic diffraction element developed by us is used for real-time analysis of the polarization state of light. The simultaneous measurement of the intensities of four beams diffracted on the element and the appropriate software enable the complete polarization state of an analyzable light (the four Stokes parameters) to be obtained in real-time. The polarization state of light reflected from the object enables to obtain the physicalchemical characteristics of the object's surface. An application of the sensor in the tasks of remote sensing and in studying a stressed state in different constructions are presented. Such sensor has many advantages compared to conventional devices of polarization optics: operation in real time; a wide spectral range; they differ by compactness, universality, simplicity, light weight and comparative cheapness.
