TECHNIQUE FOR MEASUREMENT OF GENERALIZED LASER BEAM CROSS-SECTION

摘要

A technique for measurement of the coefficient of nonuniformity of the distribution of radiation intensity and of the generalized laser beam cross-section in terms of this coefficient is evaluated by means of a thin-wire profile bolometer. The design of the bolometer is in the form of a double lattice with mutually perpendicular elements that records output signals from each of the laser beams.
