METHOD FOR DETERMINATION OF LINEAR POLARIZATION OF LASER RADIATION WITH TWO-GRID BOLOMETER

摘要

Method for measurement of linear polarization of laxer radiation with two-grate bolometer through registration of signals of bolometric lattices Uand Uby effect of laser radiation with given coefficient of dichroism of thin-wire bolometric elements of those Kwith use of multi-channel low-inertial and high-sensitive analog-digital transformer and computer. One uses two-grate bolometer with normal to each other thin-wire elements with angles of directions= 0 and. By signals of lattices one determines possible two angles of direction of linear polarization of radiation with respect to each lattice by expression.As real value of angle one takes average value of angles coinciding for moth lattices in intersection of optical beam.
