Abstract
1. Способ определения усредненных значений показателя преломления воздуха, углов боковой и вертикальной рефракции, заключающийся в том, что лазерный пучок наводят на визирную цель и принимают отраженный сигнал, который затем обрабатывают совместно с результатами измерений метеоэлементов (температуры, давления, влажности воздуха) в одной или нескольких точках трассы, на основании чего получают усредненные значения для всей трассы показателя преломления, отличающийся тем, что после наведения на визирную цель пучка лазерного излучения измеряют горизонтальную и вертикальную составляющие амплитуды колебаний этого пучка в фокальной плоскости приемного объектива (флуктуации угла прихода), по которым с учетом длины трассы и измеренных значений метеоэлементов в одной (нескольких) точках трассы вычисляют усредненные для всей трассы значения показателя преломления и углов боковой и вертикальной рефракции. ! 2. Устройство определения усредненных значений показателя преломления воздуха, углов боковой и вертикальной рефракции, содержащее лазер для наведения на цель (отражатель), приемо-передающую оптику и фотоприемник, отличающееся тем, что после приемного объектива установлен светоделитель, а в фокальной плоскости установлен фотоприемник, выполненный в виде квадрант-детектора (ПЗС-матрицы) и подключенный через блок сопряжения к процессору.1. The method of determining the average values of the refractive index of air, the angles of lateral and vertical refraction, which consists in the fact that the laser beam is aimed at the target and receive the reflected signal, which is then processed together with the measurement results of meteorological elements (temperature, pressure, humidity) in one or several points of the path, on the basis of which average values are obtained for the entire path of the refractive index, characterized in that after pointing the laser beam from the target from measure the horizontal and vertical components of the amplitude of oscillations of this beam in the focal plane of the receiving lens (fluctuations in the angle of arrival), which, taking into account the length of the path and the measured values of the weather elements at one (several) points of the path, calculate the average refractive index and the angles of the side and vertical refraction. ! 2. A device for determining the average values of the refractive index of air, angles of lateral and vertical refraction, containing a laser for aiming at the target (reflector), transceiver optics and a photodetector, characterized in that a beam splitter is installed after the receiving lens and a photodetector is installed in the focal plane, made in the form of a quadrant detector (CCD) and connected through the interface unit to the processor.
