Phase Loss of Interference Fields while passing Through Free Space |
| |
| Abstract: | The relation between the distance transmitted and the phase loss is discussed in connection with the free space interference fields, and the diffraction theory is applied for obtaining the analytical relation between the phase loss and the idistance transmitted in accordance with the secondary curved surface approxi mate, thus offering a theoretical reference for reliable interferential measure ments. |
