Effection of Gas Flow to Laser-Beam Measure

摘要：

When laser-beam passes through non-isothermal and non-isoconcentration gas, measurement result is influenced by different refractive index in gas flow layer. This paper analyses the regularities of index of refraction distribution in gas flow field, presents the factors that effect on the measurement errors, estimates the position errors of the indicating light-spot and modifies the measurement result in laser-beam measure.
