OPTOELECTRONIC ANALYSER OF OPTICAL RADIATION POLARISATION Russian patent published in 2013 - IPC G01J4/04 

FIELD: measurement equipment.

SUBSTANCE: optoelectronic analyser of optical radiation polarisation includes an optoelectric converter made in the form of a conducting film applied to a dielectric substrate and having the property of surface currents generation under action of light, and two parallel measuring electrodes arranged on film surface, a cylindrical bushing, a load-carrying bar, indication means of angular position of optoelectric converter and electric signal processing devices. Film is arranged in inclined manner on the cylindrical bushing having the possibility of being rotated relative to the load-carrying bar. Electrodes are fixed on opposite ends of the film parallel to axial cross section of cylindrical bushing, which is oriented perpendicular to the film inclination plane.

EFFECT: invention allows simplifying the structure of measuring device of laser radiation polarisation, enlarging spectrum range of its operation and increasing the allowable aperture of the analysed radiation.
