A conjugate interferometer includes a first interferometer and a second interferometer arranged so that the common optical element thereof is the respective translating mirrors of the first and second interferometers.
Claims8
A conjugate interferometer comprising:
- a source beam of light;
- a first interferometer having a first beamsplitter, first means to direct the source beam of light to said first beamsplitter, a first translatable mirror in spaced angular relation to said first beamsplitter defining a first optical path, a first fixed mirror in spaced angular relation to said first beamsplitter defining a second optical path;
- a second interferometer having a second beamsplitter, second means to direct the source beam of light to said second beamsplitter, a second translatable mirror in spaced angular relation to said second beamsplitter defining a third optical path, a second fixed mirror in spaced angular relation to said second beamsplitter defining a fourth optical path, said second translatable mirror being in back-to-back relation to said first translatable mirror;
- directing means for directing the source beam of light to either said first or said second interferometer.
