  • Method for measuring an optical length of light path and a laser interferometer for carrying same into effect
    Patent number: 4558952
    Abstract: A method for measuring an optical length of light path based on use of multiple-beam interference of light and carried into effect by forming an original light beam with two collinear components having mutually independent polarizations and different frequencies in such a manner that when forming each of the following interfering light beams from the preceding one, polarizations of the light components having different frequencies are mutually converted, whereupon the interfered light is converted into an electric signal and its phase is measured, by which the light path optical length is determined.
