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 &phgr; one takes average value of angles coinciding for moth lattices in intersection of optical beam.
