    Patent number: 5596410
    Abstract: A laser interferometer having a laser to produce a beam of light and a first beam splitter to split the beam of light into first and second portions. The first portion is directed towards a measuring interferometer and the second portion is directed toward a first regulating interferometer having a regulating section. A beam director for directing a portion of the second portion of the beam of light toward a second regulating interferometer having a regulating section. A switch connected to the second regulating interferometer which turns the second regulating interferometer on when a first output signal is less than a first predetermined maximum signal threshold value or exceeds a first predetermined minimum signal threshold value and if the second regulating interferometer has the next largest regulating section length relative to the length of the regulating section of the first regulating interferometer.
