Abstract

СПОСОБ ОПРЕДЕЛЕНИЯ РАЗМЕРА ЛАЗЕРНОГО ЛУЧА, заключающийс  в выделении части поперечного сечени  луча, пространственной модул ции в пределах выделенной части и регистрации вьщеленной части излучени  приемным устройством, отличающийс  тем, что, 1C целью повышени  точности измерений, регистрируют излучение центральной части поперечного сечени  луча/ выдел ют в выходном сигнале приемного устройства посто нную составл ющую и составл ющую с удвоенной частотой пространственной модул ции и по соотношению их амплитуд определ ют размер луча.A METHOD FOR DETERMINING A LASER BEAM SIZE, consisting in extracting a part of the beam cross section, spatial modulation within the allocated part and recording the fixed part of the radiation with a receiving device, characterized in that, 1C, to improve the accuracy of measurements, the radiation of the central part of the beam cross section is recorded / emitted in the output signal of the receiving device, the constant component and the component with the double frequency of spatial modulation and by the ratio of their amplitudes determine the size p beam.
