DEVICE TO MEASURE OPTICAL RADIATION POLARISATION PARAMETERS Russian patent published in 2011 - IPC G01J4/04 

FIELD: physics.

SUBSTANCE: proposed device comprises input forming optics and two light dividers arranged at Brewster angle with their orthogonal incidence planes arranged along analysed radiation direction. Mixing plate, shaping optics and photo receiver are arranged on the way of each light divider. Forming optics, mixing plate of second light divider channel, polarisation plane 90° rotator and first light divider mixing plate are arranged along reference optical radiation from linearly-polarised reference radiation source.

EFFECT: possibility of determining complete set of polarisation parameters.
