Original Abstract
Interferometer methods are used for the high accuracy measurement of distance by specifying the measurement of the air index. Since the measurement of the refraction index of air is in atmosphere, the refraction index of air is dependant upon temperature, pressure and humidity. For the measurement of the refraction index of air, Eden’s formula [1] is usually used. The formula depends upon the atmospheric values and the CO2 concentration.
