| Abstract;Here were described on wavelength dependency of intensity and phase changes of light wave based on refractive index fluctuation of air. And also, here was theoretically investigated changes of light waves on propagation when uniform atmospheric disturbance and propagation from sky to earth ground. As a result of calculation on wavelength correlation coefficient of intensity and phase changes, wavelength correlation coefficient of phase change at less than about ten times of wavelength difference was 1, in special. By carrying out fixed stars observation on light waves of two wavelength bands centering at 0.52 and 0.85 micron, intensities and incident angles were measured by using a quarter partition receiver. As a result, it was found that wavelength correlation coefficient of intensity and incident angle changes were 0.91 and 0.92, respectively. |
